This is a single-page reference guide for Nottinghack Wiki. If you are not familiar with wikitext and markup languages, see the tutorial on Using the Wiki.

About this Wiki

Nottinghack Wiki is powered by MediaWiki, the software used by Wikipedia. The main sources of documentation are:

This reference guide was based on the public domain Project:PD help.

Formatting Pitfalls

Beware the unexpected results shown below.

Description	You type	You get
Overlapping HTML is invalid Note: Results will vary between browsers.	Avoid <b>overlapping <i>html</b> tags</i>.	[invalid HTML output]
Multiline HTML formatting	Avoid <b>multiline html</b> formatting tags.	[invalid HTML output]
Wiki markup spanning paragraphs	Avoid '''''multiline wiki''''' markup.	Avoid *multiline* wiki markup.
Multiline wiki markup	Avoid '''''multiline wiki''''' markup.	Avoid *multiline* wiki markup.
Overlapping wiki markup Note: This is valid, but can be confusing.	Basic '''overlapping ''wiki''' markup'' works OK.	Basic overlapping wiki markup works OK.

Symbols

An HTML symbol entity is a sequence of characters that produces one particular character. For example, € produces the Euro symbol "€" and ™ produces trademark symbol "™". HTML symbol entities are allowed in MediaWiki and are sometimes used in advanced editing for two main reasons: to insert characters not normally available on keyboards and to prevent the parser from interpreting and displaying HTML tags and symbols:

&euro; → €

Green → Green

The following is a list of characters that can be produced using HTML symbols. Hover any character to find out the symbol that produces it. Some symbols not available in the current font will appear as empty squares.

Mathematical formulae

Formulae can be written in TeX using <math> tags. See wikipedia:Help:Displaying a formula for details.

Description	You type	You get
The equation of mass-energy equivalence	<math>E = mc^2 \,\!</math>	<math>E = mc^2 \,\!</math>
The convolution theorem states that...	<math> \mathcal{F}\{f * g\} = k\cdot \mathcal{F}\{f\}\cdot \mathcal{F}\{g\}</math>	<math> \mathcal{F}\{f * g\} = k\cdot \mathcal{F}\{f\}\cdot \mathcal{F}\{g\}</math>

Signatures

In some situations you may want to sign your name or indicate when a change was made. You can do this easily using the tilde character (~) as shown below. This is particularly useful on talk pages.

Function	You type	Automatically susbstituted wiki code	You get
Full signature (recommended)	~~~~	`[[User:Username\|Username]] 12:34, 1 February 2008 (UTC)`	Username 12:34, 1 February 2008 (UTC)
Signature alone	~~~	`[[User:Username\|Username]]`	Username
Timestamp alone	~~~~~	`12:34, 1 February 2008 (UTC)`	12:34, 1 February 2008 (UTC)

Layout

Section formatting can only be used at the beginning of a line. Note: Spaces at the start of a line are significant.

Headings

Headings of different levels are created by surrounding the line with equal signs (=).

== Level 2 ==
=== Level 3 ===
==== Level 4 ====
===== Level 5 =====
====== Level 6 ======

Note: Level 1 is automatically generated for the page title and is not appropriate within the body of articles.

For each heading in the wiki article an HTML anchor is automatically created. That makes it possible to create links to section headings. An article with 4 or more headings automatically shows a table of contents.

Paragraphs

MediaWiki generally ignores single line breaks and joins consecutive lines of text together. To start a new paragraph, leave an empty line. To create a wide paragraph break, leave two empty lines. You can force a line break inside a paragraph with the HTML tag  .

Description	You type	You get
Single line breaks are ignored	This text is joined together as if it were a single line.	This text is joined together as if it were a single line.
Empty lines define paragraphs Note: Two empty lines give a larger paragraph break.	First paragraph. Second paragraph. The third paragraph will <br /> break in the middle.	First paragraph. Second paragraph. The third paragraph will break in the middle.

Other section formatting

Description	You type	You get
Bullet list	* Start each line * with an [[Wikipedia:asterisk\|asterisk]] (). * More asterisks gives deeper *** and deeper levels. * Line breaks<br />don't break levels. *** But jumping levels creates empty space. Any other new line ends the list.	Start each line with an asterisk (*). More asterisks gives deeper and deeper levels. Line breaks don't break levels. But jumping levels creates empty space. Any other new line ends the list.
Numbered list	# Start each line # with a [[Wikipedia:Number sign\|number sign]] (#). ## More number signs gives deeper ### and deeper ### levels. # Line breaks<br />don't break levels. ### But jumping levels creates empty space. # Blank lines # end the list and start another. Any other new line also ends the list.	Start each line with a number sign (#). More number signs gives deeper and deeper levels. Line breaks don't break levels.

Links

There are three sorts of links:

Internal links to other pages in the wiki.
External links to other websites.
Interwiki links to other websites registered to the wiki in advance.

Internal links

To add an internal link, enclose the name of the page you want to link to in double square brackets. The first letter of the link is automatically capitalized and spaces are replaced with underscores.

Note: A red link indicates that the target page does not exist yet.

Description	You type	You get
An internal link	[[NottingHack]]	NottingHack
A piped link	[[NottingHack\|different text]]	different text
Word-endings are 'blended'	[[Help]]s [[Help]]ing [[Help]]ers [[Help]]anylettersyoulikehere [[Help]]<nowiki></nowiki>anylettersyoulikehere	Helps Helping Helpers Helpanylettersyoulikehere Helpanylettersyoulikehere

Link to a category page	[[:Category:Help]]	Category:Help
Link to an image or a file	[[media:example.jpg]]	media:example.jpg
Link to the user's user page	[[Special:MyPage]]	Special:MyPage
Additional wiki markup is permitted in link titles	[[#top\|'''<del>rich</del>''' ''link text'' here.]]	~~rich~~ link text here.

Links to section headings

You can link directly to headings within a wiki page. MediaWiki automatically creates an HTML anchor with the same name as the heading.

Description	You type	You get
Links to section headings	[[#External links\|Links]] [[#Table pitfalls!]]	Links #Table pitfalls!

Note: If a heading is renamed then any links to that heading will be broken.

External links

Description	You type	You get
External link	http://mediawiki.org	http://mediawiki.org
External link with different label	[http://mediawiki.org MediaWiki]	MediaWiki
Numbered external link	[http://mediawiki.org]	[2]
External links with file icons. See currently supported icons.	[http://en.wikipedia.org/wiki/.avi video]<br/> [http://en.wikipedia.org/wiki/.ogg sound]<br/> [http://en.wikipedia.org/wiki/.pdf document]<br/>	video sound document
External link to the same host	http://{{SERVERNAME}}/pagename	http://wiki.nottinghack.org.uk/pagename
External link to other host passing the pagename	http://google.com/search?q={{PAGENAMEE}}	http://google.com/search?q=Marcus/MediaWiki_Quick_Reference
Mailto link	[mailto:info@example.org email me]	email me
Mailto named with subject line and body	[mailto:info@example.org?Subject=URL%20Encoded%20Subject&body=Body%20Text info]	info
Additional wiki markup is permitted in link titles	[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''link text'' here.]	Example ~~rich~~ link text here.

External link icons

Test link	Icon	Trigger
[3]	external-link-ltr-icon.png	`.external`, `http://`, `gopher://`
[4]	lock-icon.png	`https://`
[5]	mail-icon.png	`mailto:`

[10]	video-icon.png	`.ogm`, `.avi`, `.mpeg`, `.mpg`
[11]	document-icon.png	`.pdf`, `.pdf#`, `.pdf?`

How to avoid auto-links

By default, when you write a URL as is, it will be transformed to an external link. To avoid that effect, put the URL between <nowiki> tags as in:

<nowiki>http://mediawiki.org</nowiki>

Interwiki links

Interwiki links are abbreviations for longer URLs. They can link to an external site almost as if they are linking to a page on Nottinghack Wiki. The external website must be registered in advance on the Special:Interwiki page.

Description	You type	You get
An interwiki link to a `wikipedia` article.	[[wikipedia:Sunflower\|big yellow flower]]	big yellow flower
A similar external link (without using an interwiki link).	[http://en.wikipedia.org/wiki/Sunflower big yellow flower]	big yellow flower

The pipe trick

The pipe trick is a quick way to abbreviate certain types of links while you are editing wiki text. Once you save the page, the abbreviations are substituted with the full versions of the links. Some examples are shown below and more details can be found in wikipedia:Help:Pipe trick and metawikipedia:Help:Piped link#Pipe trick.

Description	You type	Substitution	You get
Page title with parentheses	[[top (Unix)\|]]	[[top (Unix)\|top]]	top
Page title with commas	[[top, unix\|]]	[[top, unix\|top]]	top
Page title with namespace	[[Help:Contents\|]]	[[Help:Contents\|Contents]]	Contents
An interwiki link	[[wikipedia:top (Unix)\|]]	[[wikipedia:top (Unix)\|top]]	top

Tables

Tables can be added to wiki pages using either XHTML table elements directly, or using wikitext formatting to define the table. The benefit of wikitext is that it tends to be easier to see the table structure when editing.

As a general rule, it is best to avoid using a table unless you need one. Table markup often complicates page editing.

Wiki table markup summary

Note: The following markers must each start on a new line.

{\|	table start
\|+	table caption, optional; only between table start and the first table row
\|-	table row, optional on the first row
!	table header cell, optional.
\|	table data cell, required!
\|}	table end

These markers can also be used to write several consecutive table cells on the same line:

!!	Start a consecutive table header cell.
\|\|	Start a consecutive table data cell.

Basic table examples

The following table lacks borders and good spacing but shows the simplest wiki markup table structure.

You type

You get

{|
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}

Orange	Apple
Bread	Pie
Butter	Ice cream

The cells in the same row can be listed on one line separated by || (two pipe symbols). If the text in the cell contains a line break, use   instead.

You type

You get

{|
|Orange||Apple||more
|-
|Bread||Pie||more
|-
|Butter||Ice<br />cream||and<br />more
|}

Orange	Apple	more
Bread	Pie	more
Butter	Ice cream	and more

Extra spaces within cells in the wiki markup do not affect the actual table rendering:

You type

You get

{|
|  Orange    ||   Apple   ||   more
|-
|   Bread    ||   Pie     ||   more
|-
|   Butter   || Ice cream ||  and more
|}

Orange	Apple	more
Bread	Pie	more
Butter	Ice cream	and more

You can have longer text or more complex wiki syntax inside table cells:

You type

You get

{|
|Lorem ipsum dolor sit amet, 
consetetur sadipscing elitr, 
sed diam nonumy eirmod tempor invidunt
ut labore et dolore magna aliquyam erat, 
sed diam voluptua. 

At vero eos et accusam et justo duo dolores
et ea rebum. Stet clita kasd gubergren,
no sea takimata sanctus est Lorem ipsum
dolor sit amet. 
|
* Lorem ipsum dolor sit amet
* consetetur sadipscing elitr
* sed diam nonumy eirmod tempor invidunt
|}

Lorem ipsum dolor sit amet,

consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.

Lorem ipsum dolor sit amet
consetetur sadipscing elitr
sed diam nonumy eirmod tempor invidunt

Table headers

Table headers can be created by using "!" (exclamation mark) instead of "|" (pipe symbol). Headers usually show up bold and centered by default.

You type

You get

{|
! Item
! Amount
! Cost
|-
|Orange
|10
|7.00
|-
|Bread
|4
|3.00
|-
|Butter
|1
|5.00
|-
!Total
|
|15.00
|}

Item	Amount	Cost
Orange	10	7.00
Bread	4	3.00
Butter	1	5.00
Total		15.00

Table captions

A table caption can be added to any table as follows.

You type

You get

{|
|+Food complements
|-
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}

Food complements
Orange	Apple
Bread	Pie
Butter	Ice cream

Table attributes

The wikitext table markers can accept a space separated list of XHTML attributes. For example, this wikitext will start a row with green text:

|- style="color:green;"

In table cells and captions (| or ||, ! or !!, and |+) the attributes are separated from cell content with a single pipe character (|).

|align="right"|This is a right-aligned table cell.

For the authoritative source on XHTML attributes, see the W3C's HTML 4.01 Specification page on tables.

Attributes on entire tables

Placing attributes after the table start tag ({|) applies attributes to the entire table.

You type

You get

{| border="1" align="center" style="text-align:center;"
|Orange
|Apple
|12,333.00
|-
|Bread
|Pie
|500.00
|-
|Butter
|Ice cream
|1.00
|}

Orange	Apple	12,333.00
Bread	Pie	500.00
Butter	Ice cream	1.00

Attributes on cells

You can put attributes on individual cells. For example, numbers may look better aligned right.

You type

You get

{| border="1"
|Orange
|Apple
|align="right" | 12,333.00
|-
|Bread
|Pie
|align="right" | 500.00
|-
|Butter
|Ice cream
|align="right" | 1.00
|}

Orange	Apple	12,333.00
Bread	Pie	500.00
Butter	Ice cream	1.00

You can also use cell attributes when you are listing multiple cells on a single line. Note that the cells are separated by ||, and within each cell the attributes and cell contents are separated by |.

You type

You get

{| border="1"
| Orange || Apple     || align="right" | 12,333.00
|-
| Bread  || Pie       || align="right" | 500.00
|-
| Butter || Ice cream || align="right" | 1.00
|}

Orange	Apple	12,333.00
Bread	Pie	500.00
Butter	Ice cream	1.00

Attributes on rows

You can set attributes for individual rows.

You type

You get

{| border="1"
|Orange
|Apple
|align="right"|12,333.00
|-
|Bread
|Pie
|align="right"|500.00
|- style="font-style:italic; color:green;"
|Butter
|Ice cream
|align="right"|1.00
|}

Orange	Apple	12,333.00
Bread	Pie	500.00
Butter	Ice cream	1.00

One-pixel table borders

A one-pixel border can be achieved using separated borders or the collapsing border model.

You type

You get

{|style="border-collapse: separate; border-spacing: 0; border-width: 1px; border-style: solid; border-color: #000; padding: 0"
|-
!style="border-style: solid; border-width: 0 1px 1px 0"| Orange
!style="border-style: solid; border-width: 0 0 1px 0"| Apple
|-
|style="border-style: solid; border-width: 0 1px 0 0"| Bread
|style="border-style: solid; border-width: 0"| Pie
|}

Orange	Apple
Bread	Pie

{|style="border-collapse: collapse; border-width: 1px; border-style: solid; border-color: #000"
|-
!style="border-style: solid; border-width: 1px"| Orange
!style="border-style: solid; border-width: 1px"| Apple
|-
|style="border-style: solid; border-width: 1px"| Bread
|style="border-style: solid; border-width: 1px"| Pie
|}

Orange	Apple
Bread	Pie

HTML colspan and rowspan

You can use HTML colspan and rowspan attributes on cells for advanced layout.

You type

You get

{| border="1"
!colspan="6"|Shopping List
|-
|rowspan="2"|Bread & Butter
|Pie
|Buns
|Danish
|colspan="2"|Croissant
|-
|Cheese
|colspan="2"|Ice cream
|Butter
|Yoghurt
|}

Shopping List
Bread & Butter	Pie	Buns	Danish	Croissant
Bread & Butter	Cheese	Ice cream		Butter	Yoghurt

Table attributes with CSS styles

CSS style attributes can be added to tables with or without other HTML attributes.

You type

You get

{| style="color:green; background-color:#ffffcc;" cellpadding="10" cellspacing="0" border="1"
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}

Orange	Apple
Bread	Pie
Butter	Ice cream

Attributes can be added to the caption and headers as follows.

You type

You get

{| border="1" cellpadding="20" cellspacing="0"
|+ align="bottom" style="color:#e76700;" |''Food complements''
|-
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}

*Food complements*
Orange	Apple
Bread	Pie
Butter	Ice cream

Accessibility of table header cells

Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is displayed in a visual 2D environment, this is usually obvious. However when tables are rendered on non-visual medias, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:

You type

You get

{| border="1" cellspacing="0" cellpadding="2"
|-
!scope="col"| Item
!scope="col"| Quantity
!scope="col"| Price
|-
!scope="row"| Bread
| 0.3 kg
| $0.65
|-
!scope="row"| Butter
| 0.125 kg
| $1.25
|-
!scope="row" colspan="2"| Total
| $1.90
|}

Item	Quantity	Price
Bread	0.3 kg	$0.65
Butter	0.125 kg	$1.25
Total		$1.90

Sortable tables

To make a table sortable add class="sortable" as shown below.

You type

You get

{| class="wikitable sortable"
|+Sortable table
|-
! Letter !! Number !! Title
|-
| c || 1 || Five
|-
| b || 3 || rows
|-
| e || 5 || of
|-
| d || 2 || text
|-
| a || 0 || here.
|}

Sortable table
Letter	Number	Title
c	1	Five
b	3	rows
e	5	of
d	2	text
a	0	here.

It is also possible to make some columns sortable and others non-sortable:

You type

You get

{| class="wikitable sortable"
|+Sortable table
|-
! Letter !! class="unsortable"|Number !! Title
|-
| c || 1 || Five
|-
| b || 3 || rows
|-
| e || 5 || of
|-
| d || 2 || text
|-
| a || 0 || here.
|}

Sortable table
Letter	Number	Title
c	1	Five
b	3	rows
e	5	of
d	2	text
a	0	here.

Table pitfalls!

If you start a cell on a new line with a negative number with a minus sign (or a parameter that evaluates to a negative number), your table can get broken, because the characters |- will be parsed as the wiki markup for table row, not table cell. To avoid this, insert a space before the value (| -6) or use in-line cell markup (|| -6).

Images

Note: Images must be uploaded to the wiki before they can be used.

Supported media types for images

The following file formats are supported on Nottinghack Wiki:

.jpg or .jpeg : bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).
.png : bitmap image in the Portable Network Graphics format (specified by the W3 Consortium).
.gif : bitmap image in the legacy Graphics Interchange Format.
.svg : scalable image in the Scalable Vector Graphics format (specified by the W3 Consortium).

Uploading an image

In the sidebar, under “toolbox”, click “Upload file.”
Select the “Source filename”
You can fill in the optional “Summary” text. Note: This is a plain text summary, not wikitext.

After you upload a file, you will be redirected to the “file description page”. You should edit this page to provide more information about the file. For example, you should explain where you got the file from, and what its copyright status is.

Displaying an image

The wikitext to display an image is:

[[File:filename.extension|options|caption]]

The options can be given in any order separated by pipes (|):

border: Adds a very thin border around the image.
frame, frameless, thumb or thumbnail: Controls how the image is formatted and embedded in the rest of the page. See the examples of image formats.
{width}x{height}px: Resizes the image to fit inside a maximum {width} and {height} in pixels. See the examples of image resizing.
Note: The image will always retain its aspect ratio.
{width}px: Resizes the image using a maximum width in pixels.
x{height}px: Resizes the image using maximum height in pixels.
upright: Uses a resizing algorithm suitable for images in portrait orientation rather than landscape.
left, right, center, or none: Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).
baseline, sub, super, top, text-top, middle, bottom, or text-bottom: Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is middle).
link={target}: Allows to change the target of the generated link associated with the image. See Altering the default link target.
Note: link does not work with thumb, thumbnail or frame.
alt={alternative text}: Defines the alternative text (maps to the HTML alt="..." attribute).
page={number}: Renders the specified page number (only applicable when showing a .djvu or .pdf file).

If a parameter does not match any of the other possibilities, it is assumed to be the caption text. Caption text is shown below the image in thumb and frame formats, or as mouseover text in border and frameless formats or when the format is omitted. Caption text displayed in the thumb and frame formats may contain wiki links and other formatting. In the other options, wiki-formatting will not work. If no caption text is supplied, a caption is automatically created showing the file name. To completely remove the caption, set it to .

Image dimensions and borders

The effect of the size parameters depend on how the image is formatted, but images will always retain their aspect ratio. When the format is not specified the image can be reduced or enlarged to any size. An image with the frame format always ignores the size specification and the original image will be reduced if it exceeds a maximum size. The size of an image with the thumb format can be reduced, but can not be enlarged beyond the original image size unless it is a scalable media type.

In the examples below, the original size of the image is 400 × 267 pixels.

Format	You type	You get
(not specified)	[[File:MediaWiki:Image sample\|50px]]
(not specified)	[[File:MediaWiki:Image sample\|500px]]
border	[[File:MediaWiki:Image sample\|border\|50px]]
border	[[File:MediaWiki:Image sample\|border\|500px]]
frame	[[File:MediaWiki:Image sample\|frame\|50px]]
frame	[[File:MediaWiki:Image sample\|frame\|500px]] Note: The size parameters have no effect when using the `frame` format.
thumb	[[File:MediaWiki:Image sample\|thumb\|50px]]
thumb	[[File:MediaWiki:Image sample\|thumb\|500px]] Note: A `thumb` image cannot be enlarged beyond the size of the original image.
frameless	[[File:MediaWiki:Image sample\|frameless\|50px]]
frameless	[[File:MediaWiki:Image sample\|frameless\|500px]] Note: A `frameless` image cannot be enlarged beyond the size of the original image.

Horizontal alignment

Note that when using the frame or thumb[nail] formats, the default horizontal alignment will be right.

Description	You type	You get
no horizontal alignment specified, or default alignment Rendered as a floating block: no Rendered inline: yes	text before [[File:example.jpg\|100px\|caption]] text after	text before text after
specify horizontal alignment as: none Rendered as a floating block: no Rendered inline: no	text before [[File:example.jpg\|none\|100px\|caption]] text after	text before caption text after
specify horizontal alignment as: center Rendered as a floating block: no Rendered inline: no	text before [[File:example.jpg\|center\|100px\|caption]] text after	text before caption text after
specify horizontal alignment as: left Rendered as a floating block: yes Rendered inline: no	text before [[File:example.jpg\|left\|100px\|caption]] text after	text before caption text after
specify horizontal alignment as: right Rendered as a floating block: yes Rendered inline: no	text before [[File:example.jpg\|right\|100px\|caption]] text after	text before caption text after

Vertical alignment

The vertical alignment options take effect only if the image is displayed as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same row. Note that the displayed line of text where inline images are inserted (and the lines of text displayed after the current one) may be moved down. The line spacing will increase, just as may occur with spans of text with variable font sizes to allow the image height to be fully displayed with this alignment constraint.

To show the alignment result more clearly in this example, the text spans are overlined and underlined, the line-height is increased and emphasized with a yellow background and grey border:

~~text~~ top: ~~text~~

~~text~~ text-top: ~~text~~

~~text~~ ^super: ~~text~~

~~text~~ baseline: ~~text~~

~~text~~ _sub: ~~text~~

~~text~~ default: ~~text~~

~~text~~ middle: ~~text~~

~~text~~ text-bottom: ~~text~~

~~text~~ bottom: ~~text~~

Stopping the text flow

On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing   before the text that should start below the floating image.

All images displayed as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for centered images).

Altering the link target

The table below shows how to alter or remove the link target associated with an image. Note: The link attribute does not work with thumb or frame formats.

Description	You type	You get
internal link	[[File:example.jpg\|link=Main Page\|caption]]
external link	[[File:example.jpg\|link=http://wikipedia.org\|caption]]
no link (external or file page)	[[File:example.jpg\|link=\|caption]]

Displaying an image gallery

It's easy to make a gallery of thumbnails with the <gallery> tag:

<gallery>
Image:file_name.ext|caption
Image:file_name.ext|caption
{...}
</gallery>

Note that the image code is not enclosed in quare brackets inside gallery tags. Captions are optional, and may contain wiki links or other formatting. For example:

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg
File:Example.jpg| ''italic caption''
File:Example.jpg|on page "{{PAGENAME}}"
</gallery>

Is displayed as:

Item 1
a link to Help:Contents
italic caption
on page "Marcus/MediaWiki Quick Reference"

Optional gallery attributes

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:

<gallery {parameters}>
{images}
</gallery>

caption={caption}: A caption for the gallery.
widths={width}px: The maximum width for the images. Note the plural (widths)
heights={heights}px: The maximum height for the images.
perrow={integer}: The number of images per row.
showfilename={y or n}: Show the filenames in the image captions.

Example wikitext:

<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
</gallery>

Result:

sunflowers are groovy

Linking to an image without displaying it

Link to the description page

If you put a colon (:) before File:, the image will not be embedded and the link will lead to the description page of the file.

Description	You type	You get
Link to the description page of the file	[[:{{ns:image}}:Example.jpg]]	File:Example.jpg
Link to the description page with a custom title.	[[:{{ns:image}}:Example.jpg\|Sunflowers]]	Sunflowers

Link directly to the media file

You can use the pseudo-namespace “Media” to link directly to a file without displaying it, bypassing the description page.

Description	You type	You get
Link directly to a file.	[[{{ns:media}}:Example.jpg]]	Media:Example.jpg
Link directly to a file, with a custom title.	[[{{ns:media}}:Example.jpg\|Sunflowers]]	Sunflowers
link to a potential file, even if it doesn't exist.	[[{{#special:Filepath}}/Example.jpg]]	Special:FilePath/Example.jpg
Generate an external URL to the file	{{FILEPATH:Example.jpg}}	https://wiki.nottinghack.org.uk/images/a/a9/Example.jpg

Displaying images from other websites

Currently it is not possible to embed images from other websites into Nottinghack Wiki. Links are displayed instead. External image embedding could be enabled using mw:Manual:$wgAllowExternalImages.

Description	You type	You get
Link or embed an image from another website	http://upload.wikimedia.org/wikipedia/en/b/bc/Wiki.png	http://upload.wikimedia.org/wikipedia/en/b/bc/Wiki.png

Widgets

MediaWiki widgets allow you to embed web widgets into a wiki page. Each widget has its own documentation, which can be found in the list of available widgets.

Namespaces

Pages in MediaWiki are partitioned into 'namespaces', which indicate the purpose of the pages at a high level. Namespaces are specified in page titles by prefixing the page name with "namespace:". For example, the prefix "User:" in this page's title ("User:Marcus/MediaWiki Quick Reference") indicates that this page is in the User namespace.

Note: Colons and prefixes can also appear in page titles without indicating a namespace: The page Foo:Marcus/MediaWiki Quick Reference is a page located in the Main namespace, because the namespace "Foo" does not exist. Similarly the page User:Foo:Marcus/MediaWiki Quick Reference is in the "User" namespace.

Standard namespaces

These are the namespaces that exist on Nottinghack Wiki. Pages in some namespaces have special properties.

Namespace	Purpose and special properties
Media	An alias used to link directly to media files.
Special	Used to group special pages, reports and interfaces that are generated 'on demand' by MediaWiki and which are not directly editable.
Main	This namespace typically contains the bulk of the content pages in a wiki. It has no special properties.
Talk	Used for discussion attached to the main namespace. It has no special properties.
User	Each user has a corresponding page in the User namespace, which is linked to from edit histories, watchlists, recent changes, etc; wherever an individual user is uniquely identified. This page, and subpages of it, can be used by users to record information about themselves or to test and draft new content.
User talk	A discussion space associated with the User namespace, mainly used to leave messages for particular users or inform them of discussions that may be of interest to them.
Nottinghack Wiki	Normally used for content pages that document the operation and development of the wiki. It has no special properties.
Nottinghack Wiki talk	Normally used for discussions related to the associated content pages. It has no special properties.
File	Used to store metadata for images, videos, sound files and other media accessed via the Media namespace. Each file has a corresponding page in the File namespace which is often used to hold licensing data. Linking directly to a page in this namespace instead includes the media file inline in the page. See #Images for details of the link syntax. There is an alias "Image" for the File namespace.
File talk	Normally used for discussion of the media files. It has no special properties.
MediaWiki	Used to hold system messages and other important content.
MediaWiki talk	A talk namespace that is normally used for discussions related to the system messages. It has no special properties.
Template	Used to hold templates. To facilitate this it has the special property that it is the default namespace for transclusions.
Template talk	A talk namespace that is normally used for discussion of the template pages. It has no special properties.
Help	Used to hold help files, instructions and 'how-to' guides. It has no special properties.
Help talk	Used for discussions related to the help pages. It has no special properties.
Category	Contains categories (dynamic lists of other pages). To facilitate this, linking directly to a category page does not output an inline link, but instead adds the page into the associated category page.
Category talk	Used for discussion of the category pages. It has no special properties.

Talk pages

The MediaWiki namespaces are organised in pairs, with each pair containing a 'subject namespace' and a 'discussion namespace'. Every page in a subject namespace has an associated talk page which can be used to communicate with other users. Talk pages can be accessed by clicking the “discussion” tab at the top of a page. Simply edit the page as normal to add your comment. Also see wikipedia:Help:Using talk pages.

User pages

A user page in the User namespace is a page about a member of the wiki. If you have registered, you can create your own user page. Your user page is linked in the top right. Others will see links to your user page from various places which assist wiki collaboration, including the “Recent changes” and “page history” pages. Every user page also has an associated "user talk page". This is a special kind of talk page, for leaving messages directed at a particular user. Also see Wikipedia:User pages.

Subpages

Subpages introduce hierarchical organization into wiki pages, with levels of the hierarchy separated by slashes (/).

Where it works

By default, MediaWiki's subpage feature is turned off in the main namespace, but can be used on talk pages and user pages. In namespaces where the feature is switched off, any slashes (/) within a page name are simply part of the page name and do nothing special.

How it works

Slashes (/) within a page name break the page into parent and subpages, recursively, e.g.:

User:Marcus/MediaWiki Quick Reference - this page
User:Marcus/MediaWiki Quick Reference/subpage - child page
User:Marcus/MediaWiki Quick Reference/subpage/sub-subpage - grandchild page

Note that the part of page names after a slash is case sensitive. In subpages, a link back to the parent page will automatically appear at the top.

Use of subpages

Some typical uses for subpages are:

to create archives of old discussions under a talk page
to create scratchpad editing spaces under a user page

Subpages are useful for organising information hierarchically. On the other hand, subpages tend to have a long name that is hard to remember, so it may be more user-friendly to use them as little as possible. You can also organize pages with the category feature, which is more suitable for creating a hierarchical network of information.

Templates

MediaWiki templates can be used to include standard messages on several wiki pages. If you change a template then the text will be updated on all of the pages where it is used.

Template creation

Templates are standard wiki pages whose content is designed to be transcluded. You can create them like any other wiki page. Templates follow a convention that the name is prefixed with "Template:".

Using templates

The tag {{Name}} transcludes the content of a template (stored in the page [[Template:Name]]). For example, if you have a page called "Template:Welcome" with the contents:

Hello! Welcome to the wiki.

You can insert the code {{Welcome}} in any other page, and when that page is viewed the text "Hello! Welcome to the wiki." will appear.

An ordinary wiki page can also be used as a template, simply by specifying the full name with the namespace:

{{:Pagename}} includes [[Pagename]]
{{Foo:Pagename}} includes [[Foo:Pagename]]

Controlling the time of transclusion

You write	Effect
`{{Name}}`	Transcludes the content of the template (stored in the page [[Template:Name]]) every time the page is fetched and displayed. If the template is later changed, the transcluding pages will automatically change too.
`{{msgnw:Name}}`	Includes the template in a form that displays it as raw wiki syntax (the way `<nowiki>` does).
`{{subst:Name}}`	This tag is substituted with the contents of the named template at the time you save the page. The contents can then be edited separately from the original in the template page. Note: don not use this if you want to continually propagate changes from the source template to the pages that reference it.
`{{safesubst:Name}}`	A type of substitution that doesn't break transclusion, see wikipedia:Help:Substitution#The safesubst: modifier.

Parameters

MediaWiki allows parameters to be passed to a template when it is transcluded. There are three ways to pass parameters: anonymously, by number, and by name.

To pass in anonymous parameters to a template, list the values of those parameters sequentially:

{{Thankyou|all your effort|Joe}}

Inside the template these parameters can be accessed by number:

{{{1}}} → all your effort

{{{2}}} → Joe

To pass in parameters by number, identify each parameter when passing it:

{{Thankyou|2=Joe|1=all your effort}}

The third way of passing parameters is by name, instead of numbers.

{{Thankyou|signature=Joe|reason=all your effort}}

Inside the template these parameters can be accessed by name:

{{{signature}}} → Joe

{{{reason}}} → all your effort

The advantage of using named parameters in your template, besides also being flexible in the order parameters can be passed, is that it makes the template code much easier to understand if there are many parameters.

Default values

It is possible to define default values for parameters in case no value is passed in. The syntax to retrieve a parameter using a default value is:

{{{ParameterName|DefaultValue}}}

The default parameter can be ommitted, in which case it defaults to an empty string:

{{{ParameterName|}}}

Control template inclusion

Anything between <noinclude> and </noinclude> will be displayed only when the template page is viewed directly.

Possible applications are:

Categorising templates
Explanatory text about how to use the template.

To give usage information, include an example like this one on the template page:

<noinclude>
== Usage ==
{{Thankyou|reason=your reason|signature=your signature}}
</noinclude>

The converse is <includeonly>. Text between <includeonly> and </includeonly> will be processed and displayed only when the page is being included. The obvious application is to add all pages containing a given template to a category, without putting the template itself into that category. Notw: When you change the categories applied by a template, the categorization of the pages that use that template may not be updated until some time later.

Organizing templates

For templates to be effective, users need to find them, and find out how to use them. For a list of all templates, see Special:Allpages/Template:.

Redirects

Redirects are used to forward users from one page name to another. They can be useful if a particular article is referred to by multiple names, or has alternative punctuation, capitalization or spellings.

Creating a redirect

You may start a new page with the name you want to direct from (see Starting a new page). You can also use an existing page that you are making inactive as a page by going to that page and using the "edit" tab at the top. In either case, insert the following code at the very start of the Edit window for the page:

#REDIRECT [[pagename]]

where pagename is the name of the destination page. There must be no space before the "#" symbol. Any text before the code will disable the code and prevent a redirect.

Double redirects

A double redirect is a page redirecting to a page which is itself a redirect, and it will not work. Instead, people will be presented with a view of the next redirect page. This is a deliberate restriction, partly to prevent infinite loops, and partly to keep things simple. Double redirects should be eliminated by changing them to be 1-step redirects instead. Use the "what links here" toolbox link to find double redirects to a particular page, or use Special:DoubleRedirects to find them throughout the whole wiki.

A redirect to a page in the category namespace

To prevent a page that redirects to a category from appearing in the category, precede the word "Category" with a colon:

#REDIRECT [[:Category:Glossary]]

Magic Words

Magic words are strings of text that MediaWiki interprets as a value or function. Page-dependent magic words will affect or return data about the current page (by default), even if the word is added through a transcluded template or included system message.

Behavior switches

A behavior switch controls the layout or behaviour of the page and can often be used to specify desired omissions and inclusions.

Word	Description
`__NOTOC__`	Hides the table of contents (TOC).
`__FORCETOC__`	Forces the table of contents to appear at its normal position (above the first header).
`__TOC__`	Places a table of contents at the word's current position (overriding `__NOTOC__`). If this is used multiple times, the table of contents will appear at the first word's position.
`__NEWSECTIONLINK__`	Adds a link ("+" by default) beside the "edit" tab for adding a new section on a non-talk page (see Adding a section to the end).
`__NOINDEX__`	Tell search engines not to index the page (ie, do not list in search engines' results).

Variables

Variables return information about the current page, wiki, or date. Their syntax is similar to templates.

Technical metadata

Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

Variable	Output	Description

`{{PROTECTIONLEVEL:action}}`	protection level	The protection level (e.g. 'autoconfirm', 'sysop') for a given action (e.g. 'edit', 'move') on the current page or an empty string if not protected.
Affects page content
`{{DISPLAYTITLE:title}}`		Format the current page's title. The value must be equivalent to the default title: only capitalization changes and replacing spaces with underscores are allowed.
`{{DEFAULTSORT:sortkey}}` `{{DEFAULTSORTKEY:sortkey}}` `{{DEFAULTCATEGORYSORT:sortkey}}`		Used for categorizing pages, sets a default category sort key. For example if you put `{{DEFAULTSORT:Smith, John}}` at the end of John Smith, the page would be sorted under "S" by default in categories.

Statistics

Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, {{NUMBEROFPAGES}} → 5,473 and {{NUMBEROFPAGES:R}} → 5473). Use "|R" for magic words that require a parameter like PAGESINCATEGORY (for example {{PAGESINCATEGORY:Help}} and {{PAGESINCATEGORY:Help|R}}). Also applicable to {{PAGESIZE:page name}} above.

Variable	Output	Description
Entire wiki
`{{NUMBEROFPAGES}}`	5,473	Number of wiki pages.
`{{NUMBEROFARTICLES}}`	974	Number of pages in content namespaces.

Variable	Output	Description
`{{FULLPAGENAME}}`	User:Marcus/MediaWiki Quick Reference	Namespace and page title.
`{{PAGENAME}}`	Marcus/MediaWiki Quick Reference	Page title.
`{{BASEPAGENAME}}`	Marcus	Page title excluding the current subpage and namespace. For more complex splitting, use `{{#titleparts:}}`.
`{{SUBPAGENAME}}`	MediaWiki Quick Reference	The subpage title.
`{{SUBJECTPAGENAME}}`	User:Marcus/MediaWiki Quick Reference	The namespace and title of the associated content page.
`{{TALKPAGENAME}}`	User talk:Marcus/MediaWiki Quick Reference	The namespace and title of the associated talk page.

{{FULLPAGENAMEE}}
{{PAGENAMEE}}
{{BASEPAGENAMEE}}
{{SUBPAGENAMEE}}
{{SUBJECTPAGENAMEE}}
{{TALKPAGENAMEE}}

These can all take a parameter allowing specification of the page to be operated on, instead of just the current page:

{{PAGENAME:Template:Main Page}} → Main Page

{{TALKSPACEE}}

These can take a page name instead of operating on the current page:

{{NAMESPACE:Template:Main Page}} → Template
{{SUBJECTSPACE:Template:Main Page}} → Template
{{TALKSPACE:Template:Main Page}} → Template talk

Parser functions

Parser functions have the same syntax as templates. The names are sometimes prefixed with a hash to distinguish them from template page names.

Conditional expressions

#if

This function tests whether the first parameter is non-empty. It evaluates to false if the test string is empty or contains only whitespace characters (spaces, newlines, etc).

{{#if: test string | value if true | value if false }}

#ifeq

This parser function compares two strings and determines whether they are identical.

{{#ifeq: string 1 | string 2 | value if identical | value if different }}

#iferror

This function evaluates to true if the input string contains an HTML object with class="error", as generated by other parser functions such as #expr, #time and #rel2abs, template and errors such as loops and recursions.

{{#iferror: test string | value if error | value if correct }}

#ifexpr

This function evaluates a mathematical expression and returns one of two strings depending on the boolean value of the result:

{{#ifexpr: expression | value if true | value if false }}

#ifexist

This function returns one of two values depending on whether a page exists on the local wiki.

{{#ifexist: page title | value if the page exists | value if it doesn't exist }}

#switch

This function compares one input value against several test cases, returning an associated string if a match is found.

{{#switch: comparison string
 | case1 = result1
 | case2 = result2
 | ...
 | caseN = resultN
 | default result0
}}

In `path</path> the following syntax is valid: . → the current level .. → "go up one level" /foo → "go into the subdirectory /foo" If base path is not specified, the full page name of the page will be used instead.`

Date and time functions

Variable	Output	Description
`{{#timel: Y F d, h:i:s}}`	2024 November 27, 03:16:23	Displays the current time and date in the local timezone of the wiki. Due to caching, these variables frequently show when the page was cached rather than the current time.

Namespace functions

{{ns:}} returns the localized name for a namespace. {{nse:}} is the equivalent encoded for MediaWiki URLs. It does the same, but it replaces spaces with underscores, making it usable in external links.

If the `number of segments` parameter is not specified, it defaults to "0", which returns all the segments. If the `first segment` parameter is not specified or is "0", it defaults to "1":

Miscellaneous functions

Usage	Output	Description
`{{#special:special page name}} {{#special:userlogin}}`	Special:Special page name Special:UserLogin	The localized name for the given Special: page.
`{{gender:username \|return text if user is male \|return text if user is female \|return text if user hasn't defined their gender}}`	(depends on the named user's gender)	A switch for the gender set in Special:Preferences Note: If 3rd parameter is omitted and user hasn't defined his/her gender, then `text if user is male` is returned.

Managing files and pages

Starting a new page

When a link points to an article that doesn't exist yet, the link will be coloured red. Clicking a red link will take you to the edit page where you can submit the new article. Usually this is the best way to create a new page, because it means that right from the start the page will be linked from at least one other place on the wiki. Normally there is no reason to create a page without first creating a red link to it. An alternative is to search for a page that doesn't exist (using the search box), which will provide a link to create a new stand-alone page.

Copying a page

There is no facility to copy a page in MediaWiki, so you must copy and paste the wikitext. It is not possible to copy the edit history from one page to another.

Moving (renaming) a page

The name of a page can be changed by using the "move" tab at the top. This tab is only visible if you are logged in. By using this feature, you also move the editing history of the page, which allows people to see how the contents of the page were built up, and who contributed what. Because the move operation leaves behind a redirect (see Redirects), it should not result in any broken links, however you might want to find pages which link to the old title, and change their text to link directly to the new title (see Unlinking a page).

Deciding on a page title can be a difficult aspect of wiki organization, and one which can provoke debates. If the move could be considered controversial, you should propose the move first (see Project:Propose a page move).

As with all wiki editing, a move operation can be reversed. To reverse a move operation, simply move the page back to the previous name. If a page is renamed from "A" to "B" and then back to "A", a page with the title "B" will still be left behind, as a redirect from "B" to "A". To remove this page see deleting a page). Alternatively, users with the suppressredirect permission will see the option to move a page without creating a redirect.

Deleting a page

Normal users cannot permanently delete a wiki page. This is a deliberate design feature; every kind of editing operation can be reverted and that includes resurrecting deleted pages. If for some reason you need a page to be deleted urgently, please see Project:Mark a page for deletion. For any other deletion that might be controversial or disruptive, you should propose the change first (see Project:Propose a page deletion).

Unlinking a page

The "What links here" feature in the Tools (at the bottom of the sidebar) will tell you which other Wiki pages link to the current page. Always use this feature to check before deleting a page. These related pages will need to be edited for their links to reflect the change.

-Section formatting can only be used at the beginning of a line.  {{note|Blank spaces at the start of a line are significant.}}
-=== Headings ===
-Headings of different levels are created by surrounding the line with equal signs (=).

+An HTML symbol entity is a sequence of characters that produces one particular character. For example, <code>&amp;euro;</code> produces the Euro symbol "<code>&euro;</code>" and <code>&amp;trade;</code> produces trademark symbol "<code>&trade;</code>".  HTML symbol entities are allowed in MediaWiki and are sometimes used in advanced editing for two main reasons: to insert characters not normally available on keyboards and to prevent the parser from interpreting and displaying HTML tags and symbols:
-<small>Small text with <big>larger</big> text inside</small>
+:<tt>&amp;amp;euro;</tt>&nbsp;&rarr; '''<tt>&amp;euro;</tt>'''

-== Links ==
+== Layout ==
-There are three sorts of links:
+Section formatting can only be used at the beginning of a line.  {{note}} Spaces at the start of a line are significant.
-# '''[[#Internal links|Internal links]]''' to other pages in the wiki.
-# '''[[#External links|External links]]''' to other websites.
+=== Headings ===
-# '''[[#Interwiki links|Interwiki links]]''' to other websites registered to the wiki in advance.
+Headings of different levels are created by surrounding the line with equal signs (=).
+<pre>
+== Level 2 ==
+=== Level 3 ===
+==== Level 4 ====
+===== Level 5 =====
+====== Level 6 ======
+</pre>
+{{note|Level 1 is automatically generated for the page title and is not appropriate within the body of articles.}}
+For each heading in the wiki article an HTML anchor is automatically created.  That makes it possible to create [[#Links to section headings|links to section headings]].  An article with 4 or more headings automatically shows a table of contents.
-=== Internal links ===
+=== Paragraphs ===
-To add an internal link, enclose the name of the page you want to link to in double square brackets. When you save the page, you'll see the new link pointing to your page. If the page exists already it is displayed in blue, if it does not, in red.
-The first letter of the target page is automatically capitalized, unless otherwise set by the admins, and spaces are represented as underscores (typing an underscore in the link will have a similar effect as typing a space, but is not recommended, since the underscore will also be shown in the text).
+MediaWiki generally ignores single line breaks and joins consecutive lines of text together.  To start a new paragraph, leave an empty line.  To create a wide paragraph break, leave two empty lines.  You can force a line break inside a paragraph with the HTML tag <code>&lt;br /></code>.

+{{note|This is deprecated, so use the css method instead.}}
+| <pre>
-==== How to avoid auto-links ====
+text above<center>centered</center>text below
-By default, when you write a URL as is, it will be transformed to an external link.
+</pre>
-To avoid that effect, put the URL between <code>&lt;nowiki&gt;</code> tags as in:
- <nowiki><nowiki>http://mediawiki.org</nowiki></nowiki>
-=== Interwiki links ===
-Interwiki links are abbreviations for longer URLs.  They allow you to link to an external wiki almost as if you are linking to a page on your own wiki.  The external website must be registered in advance by an administrator.
-For example, you can link to the Sunflower article on http://en.wikipedia.org by typing <code><nowiki>[[wikipedia:Sunflower]]</nowiki></code>, which will result in a link [[wikipedia:Sunflower]]. This is because <code><nowiki>http://en.wikipedia.org/wiki/</nowiki></code> is registered to {{SITENAME}} by default with the prefix of <code>wikipedia</code>.  A similar link could be created as a normal external link by typing <code><nowiki>[http://en.wikipedia.org/wiki/Sunflower big yellow flower]</nowiki></code>.
-{{note|Admins can edit the {{mediawiki|Manual:Interwiki table|interwiki table}} on this site.  See the {{mediawiki|Extension:InterWiki|InterWiki extension}}}}.
-The default Interlink map can be found in [http://www.mediawiki.org/wiki/Interwiki_map].
-== Tables ==
-'''Tables''' may be authored in wiki pages using either XHTML table elements directly, or using wikicode formatting to define the table. XHTML table elements and their use are well described on various web pages and will not be discussed here. The benefit of wikicode is that the table is constructed of character symbols which tend to make it easier to perceive the table structure in the article editing view compared to XHTML table elements.
-As a general rule, it is best to avoid using a table unless you need one. Table markup often complicates page editing.

-| '''table header''' cell, ''optional.'' Consecutive '''table header''' cells may be added on same line separated by double marks (<code>!!</code>) or start on new lines, each with its own single mark (<code>!</code>).
-|-

- <nowiki>|</nowiki>
-| '''table data''' cell, ''required!'' Consecutive '''table data''' cells may be added on same line separated by double marks (<code><nowiki>||</nowiki></code>) or start on new lines, each with its own single mark (<code><nowiki>|</nowiki></code>).
-|-
-|
- <nowiki>|}</nowiki>
-| '''table end'''
 |}
-*The above marks must '''start on a new line''' except the double <code>||</code> and <code>!!</code> for optionally adding consecutive cells to a line. However, blank spaces at the beginning of a line are ignored.
-*'''XHTML attributes.''' Each mark, except table end, optionally accepts one or more XHTML attributes. Attributes must be on the same line as the mark. Separate attributes from each other with a single space.
-**Cells and caption (<code>|</code> or <code>||</code>, <code>!</code> or <code>!!</code>, and <code>|+</code>) hold content. So separate any attributes from content with a single pipe (<code>|</code>). Cell content may follow on same line or on following lines.
-**Table and row marks (<code>{|</code> and <code>|-</code>) do not directly hold content. Do ''not'' add pipe (<code>|</code>) after their optional attributes. If you erroneously add a pipe after attributes for the table mark or row mark the parser will delete it ''and'' your final attribute if it was touching the erroneous pipe!
-*'''Content''' may (a) follow its cell mark on the same line after any optional XHTML attributes or (b) on lines below the cell mark. Content that uses wiki markup that itself needs to start on a new line, such as lists, headings, or nested tables, must be on its own new line.
-**'''Pipe character as content.''' To insert a pipe (<code>|</code>) character into a table use the &lt;nowiki&gt;<code>|</code>&lt;/nowiki&gt; escaping markup
-=== Basics ===
+== Links ==
-The following table lacks borders and good spacing but shows the simplest wiki markup table structure.
+There are three sorts of links:
+# '''[[#Internal links|Internal links]]''' to other pages in the wiki.
+# '''[[#External links|External links]]''' to other websites.
+# '''[[#Interwiki links|Interwiki links]]''' to other websites registered to the wiki in advance.

-=== XHTML attributes ===
+==== How to avoid auto-links ====
-You can add XHTML attributes to tables. For the authoritative source on these, see [http://www.w3.org/TR/REC-html40/struct/tables.html the W3C's HTML 4.01 Specification page on tables].
+By default, when you write a URL as is, it will be transformed to an external link.  To avoid that effect, put the URL between <code>&lt;nowiki&gt;</code> tags as in:
+ <nowiki><nowiki>http://mediawiki.org</nowiki></nowiki>
-==== Attributes on tables ====
+=== Interwiki links ===
-Placing attributes after the table start tag (<code>{|</code>) applies attributes to the entire table.
+Interwiki links are abbreviations for longer URLs.  They can link to an external site almost as if they are linking to a page on {{SITENAME}}.  The external website must be registered in advance on the [[{{ns:Special}}:Interwiki]] page.

+== Tables ==
-|-
+'''Tables''' can be added to wiki pages using either XHTML table elements directly, or using wikitext formatting to define the table.  The benefit of wikitext is that it tends to be easier to see the table structure when editing.
-|Bread
-|Pie
+As a general rule, it is best to avoid using a table unless you need one. Table markup often complicates page editing.
-|align="right"|500.00

-You can also use '''cell''' attributes when you are listing multiple '''cells''' on a single line. Note that the '''cells''' are separated by <code>||</code>, and within each '''cell''' the attribute(s) and value are separated by <code>|</code>.

-===== Simple one-pixel table border =====
+The cells in the same row can be listed on one line separated by <code>||</code> (two pipe symbols). If the text in the cell contains a line break, use <code><nowiki><br /></nowiki></code> instead.
-The default table formatting uses the "border-collapse: separate" model, which adds table cell spacing (which also separates the table outer border from its content cells). Even with a zero cellspacing, the borders of consecutive cells (and of the overall table container) will add up, so to get a one-pixel separation between cells, you need to selectively remove one or more of the four borders of cells.
-Such tables may be formatted more simply, using the "border-collapse: collapse" CSS property; in this table formatting model, the cellspacing attribute (or the CSS "border-spacing:" property) and the table's "padding:" CSS property is ignored and only the larger border of adjacent inner cells (or the table border for outer cells) will be used.

-Notes :
+You can have longer text or more complex wiki syntax inside table cells:
-* When using the "border-width:" CSS shortcut property, the order of the four space-separated specified values is: top, right, bottom, left. As an example from above:
-::"border-width: 0 1px 0 0"
-:When there are fewer than 4 values, the value for left takes its default from the value for right, the value for bottom takes its default from the value for top, and the value for right takes its default from the value for top.
-* The HTML attributes (such as "width=", "border=", "cellspacing=", "cellpadding=") do not need any length unit (the pixel unit is assumed). The CSS style properties (which override the HTML attributes) require an explicit length unit (if the value is not 0) such as "px" for the pixel.
-==== HTML colspan and rowspan ====
-You can use HTML '''colspan''' and '''rowspan''' attributes on cells for advanced layout.

-==== Accessibility of table header cells ====
+=== Table attributes ===
-Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is rendered in a visual 2D environment, this is usually easy to infer.
+The wikitext table markers can accept a space separated list of XHTML attributes.  For example, this wikitext will start a row with green text:
+ |- style="color:green;"
+In table cells and captions (<code>|</code> or <code>||</code>, <code>!</code> or <code>!!</code>, and <code>|+</code>) the attributes are separated from cell content with a single pipe character (<code>|</code>).
+ |align="right"|This is a right-aligned table cell.
+For the authoritative source on XHTML attributes, see [http://www.w3.org/TR/REC-html40/struct/tables.html the W3C's HTML 4.01 Specification page on tables].
-However when tables are rendered on non-visual medias, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:
+==== Attributes on entire tables ====
+Placing attributes after the table start tag (<code>{|</code>) applies attributes to the entire table.

-=== Pitfalls! ===
-==== Negative numbers ====
-If you start a cell on a new line with a negative number with a minus sign (or a parameter that evaluates to a negative number), your table can get broken, because the characters <code>|-</code> will be parsed as the wiki markup for table row, not table cell. To avoid this, insert a space before the value (<code>| -6</code>) or use in-line cell markup (<code>|| -6</code>).
-== Images ==
+You can also use cell attributes when you are listing multiple cells on a single line. Note that the cells are separated by <code>||</code>, and within each cell the attributes and cell contents are separated by <code>|</code>.
-This section explains the '''image''' syntax used in the wiki. You or another user must usually [[Help:Managing files|upload an image]] before you can use it on a page.
+{| cellspacing="0" border="1"
+!style="width:50%"|You type
-=== Supported media types for images ===
+!style="width:50%"|You get
-The following file formats are supported by Mediawiki by default:
+|-
-* '''.jpg''' or '''.jpeg''' : bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).
+|
-* '''.png''' : bitmap image in the ''Portable Network Graphics'' format (specified by the ''W3 Consortium'').
+<pre>
-* '''.gif''' : bitmap image in the legacy ''Graphics Interchange Format''.
+{| border="1"
+| Orange || Apple     || align="right" | 12,333.00

+| Butter || Ice cream || align="right" | 1.00

-==== Syntax ====
+</pre>
-The full syntax for displaying an image is:
+|
- <nowiki>[[</nowiki>File:''filename.extension''|''options''|''caption'']]
+{| border="1"
+| Orange || Apple     || align="right" | 12,333.00
-The ''options'' can be given in any order separated by pipes ('''|'''):
+|-
-* ''Format'' option: <code>frame</code>, <code>frameless</code> or <code>thumb</code>;
+| Bread  || Pie       || align="right" | 500.00
-*: Controls how the rendered image is formatted and embedded in the rest of the page. See below.
-* ''[[#Size and Frame|Resizing]]'' option: one of
-** ''{width}''<code>px</code> — Resizes the image to fit within the given maximum width in pixels, without restricting its height;
-** <code>x</code>''{height}''<code>px</code> — Resizes the image to fit within the given maximum height in pixels, without restricting its width;
-** ''{width}''<code>x</code>''{height}''<code>px</code> — Resizes the image to fit within the given width and height in pixels;
-** <code>upright</code> — Resizes an image to fit within reasonable dimensions, according to user preferences (suitable for images in portrait orientation rather than landscape).
-*: {{note|that the image will always retain its aspect ratio, and can only be reduced (not increased) in size unless it's in a scalable media type (bitmap images cannot be scaled up).  The default maximum size depends on the ''format'' and the internal image dimensions (according to its media type).}}
-* ''[[#Horizontal alignment|Horizontal alignment]]'' option: one of <code>left</code>, <code>right</code>, <code>center</code>, <code>none</code>;
-*: Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).
-* ''[[#Vertical alignment|Vertical alignment]] option'': one of <code>baseline</code>, <code>sub</code>, <code>super</code>, <code>top</code>, <code>text-top</code>, <code>middle</code>, <code>bottom</code>, '''text-bottom</code>;
-*: Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is <code>middle</code>).
-* ''[[#Altering the default link target|Link]] option'': one of
-** <code>link=</code>''{target}'' — Allows to change the target (to an arbitrary page title, or URL) of the generated link associated with the image.  {{note|<code>link</code> does '''not''' work with <code>thumb</code>, <code>thumbnail</code> or <code>frame</code>.}}
-* Other specific options:
-**  <code>border</code> — adds a very thin border around the image.
-** <code>alt=</code>''{alternative text}'' — Defines the alternative text (maps to the HTML attribute <code>alt="..."</code> of the generated <code>&lt;image /&gt;</code> element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).
-** <code>page=</code>''{number}'' — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file).
-If a parameter does not match any of the other possibilities, it is assumed to be the caption text.  Caption text is shown below the image in '''thumb''' and '''frame''' formats, or as mouseover text in '''border''' and '''frameless''' formats or when the format is omitted.  Caption text displayed in the '''thumb''' and '''frame''' formats may contain wiki links and other formatting.  In the other options, wiki-formatting will not work.  If no caption text is supplied, a caption is automatically created showing the file name.  To completely remove the caption, set it to <code><nowiki><span title=""></span></nowiki></code>.
-==== Size and Frame ====
-Among different formats, the effect of the size parameter may be different, as shown below.
-* When the format is not specified the size can be both reduced and enlarged to any specified size.
-* In the examples below, the original size of the image is 400 × 267 pixels.
-* An image with <code>frame</code> always ignores the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.
-* The size of an image with <code>thumb</code> can be reduced, but can not be enlarged beyond the original size of the image.

-==== Vertical alignment ====
+==== One-pixel table borders ====
-The vertical alignment options take effect only if the image '''is''' rendered as an inline element and '''is not''' floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.  Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.
+A one-pixel border can be achieved using [http://www.w3.org/TR/CSS2/tables.html#separated-borders separated borders] or the [http://www.w3.org/TR/CSS2/tables.html#collapsing-borders collapsing border] model.
-To show the alignment result more clearly in this example, the text spans are overlined and underlined, the line-height is increased and emphasized with a yellow background and grey border:

-==== Stopping the text flow ====
+!style="width:50%"|You type
-On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image.  Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, <nowiki>== My Header ==</nowiki>) to appear to the right of the image, instead of below it, as a user may expect.  The text flow can be stopped by placing '''<nowiki><br style="clear: both" /></nowiki>''' before the text that should start below the floating image.
+!style="width:50%"|You get
+|-
-All images rendered as blocks (including non-floating '''center'''ed images, '''left'''- or '''right'''-floating images, as well as '''framed''' or '''thumbnail'''ed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).

-=== Rendering a gallery of images ===
+==== Accessibility of table header cells ====
+Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is displayed in a visual 2D environment, this is usually obvious.  However when tables are rendered on non-visual medias, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:
-==== Gallery syntax ====
-It's easy to make a gallery of '''thumbnails only''', not other images, with the <code><nowiki><gallery></nowiki></code> tag. The syntax is:
- <nowiki><gallery></nowiki>
- Image:file_name.ext|caption
-  Image:file_name.ext|caption
- {...}
- </gallery>
-Note that the image code is not enclosed in brackets when enclosed in gallery tags.
-Captions are optional, and may contain wiki links or other formatting.

-* <code>caption={caption}</code>: sets a caption on the gallery.
+=== Sortable tables ===
-* <code>widths={width}px</code>: sets the widths of the images, default 120px. ''Note the plural, width'''s'''''
+To make a table sortable add <code>class="sortable"</code> as shown below.
-* <code>heights={heights}px</code>: sets the (max) heights of the images.
-* <code>perrow={integer}</code>: sets the number of images per row.
-* <code>showfilename={anything}</code>: Show the filenames of the images in the individual captions for each image (1.17+)

+=== Table pitfalls! <!--Note: the title of this section is used to demonstrate "Links to section headings". -->===
+If you start a cell on a new line with a negative number with a minus sign (or a parameter that evaluates to a negative number), your table can get broken, because the characters <code>|-</code> will be parsed as the wiki markup for table row, not table cell. To avoid this, insert a space before the value (<code>| -6</code>) or use in-line cell markup (<code>|| -6</code>).
+== Images ==
+{{note|Images must be uploaded to the wiki before they can be used.}}
+=== Supported media types for images ===
+The following file formats are supported on {{SITENAME}}:
+* '''.jpg''' or '''.jpeg''' : bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).
+* '''.png''' : bitmap image in the ''Portable Network Graphics'' format (specified by the ''W3 Consortium'').
+* '''.gif''' : bitmap image in the legacy ''Graphics Interchange Format''.
+* '''.svg''' : scalable image in the ''Scalable Vector Graphics'' format (specified by the ''W3 Consortium'').
+=== Uploading an image ===
+# In the sidebar, under “toolbox”, click “Upload file.”
+# Select the “Source filename”
+# You can fill in the optional “Summary” text. {{note}} This is a plain text summary, not wikitext.
+After you upload a file, you will be redirected to the “file description page”.  You should edit this page to provide more information about the file. For example, you should explain where you got the file from, and what its copyright status is.
+=== Displaying an image ===
+The wikitext to display an image is:
+ <nowiki>[[</nowiki>File:''filename.extension''|''options''|''caption'']]
+The ''options'' can be given in any order separated by pipes ('''|'''):
+; <code>border</code>
+: Adds a very thin border around the image.
+; <code>frame</code>, <code>frameless</code>, <code>thumb</code> or <code>thumbnail</code>
+: Controls how the image is formatted and embedded in the rest of the page. See the [[#Image dimensions and borders|examples of image formats]].
+; <code>''{width}''x''{height}''px</code>
+: Resizes the image to fit inside a maximum ''{width}'' and ''{height}'' in pixels. See the [[#Image dimensions and borders|examples of image resizing]]. {{note|The image will always retain its aspect ratio.}}
+; <code>''{width}''px</code>
+: Resizes the image using a maximum width in pixels.
+; <code>x''{height}''px</code>
+: Resizes the image using maximum height in pixels.
+; <code>upright</code>
+: Uses a resizing algorithm suitable for images in portrait orientation rather than landscape.
+; <code>left</code>, <code>right</code>, <code>center</code>, or <code>none</code>
+: Controls the [[#Horizontal alignment|horizontal alignment]] (and inline/block or floating styles) of the image within a text (no default value).
+; <code>baseline</code>, <code>sub</code>, <code>super</code>, <code>top</code>, <code>text-top</code>, <code>middle</code>, <code>bottom</code>, or <code>text-bottom</code>
+: Controls the [[#Vertical alignment|vertical alignment]] of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is <code>middle</code>).
+; <code>link=''{target}''</code>
+: Allows to change the target of the generated link associated with the image.  See [[#Altering the default link target|Altering the default link target]].  {{note|<code>link</code> does '''not''' work with <code>thumb</code>, <code>thumbnail</code> or <code>frame</code>.}}
+; <code>alt=''{alternative text}''</code>
+: Defines the alternative text (maps to the [http://www.w3.org/TR/html401/struct/objects.html#h-13.8 HTML <code>alt="..."</code> attribute]).
+; <code>page=''{number}''</code>
+: Renders the specified page number (only applicable when showing a .djvu or .pdf file).
+If a parameter does not match any of the other possibilities, it is assumed to be the caption text.  Caption text is shown below the image in '''thumb''' and '''frame''' formats, or as mouseover text in '''border''' and '''frameless''' formats or when the format is omitted.  Caption text displayed in the '''thumb''' and '''frame''' formats may contain wiki links and other formatting.  In the other options, wiki-formatting will not work.  If no caption text is supplied, a caption is automatically created showing the file name.  To completely remove the caption, set it to <code><nowiki><span title=""></span></nowiki></code>.
+==== Image dimensions and borders ====
+The effect of the size parameters depend on how the image is formatted, but images will always retain their aspect ratio.  When the format is not specified the image can be reduced or enlarged to any size.  An image with the <code>frame</code> format always ignores the size specification and the original image will be reduced if it exceeds a maximum size.  The size of an image with the <code>thumb</code> format can be reduced, but can not be enlarged beyond the original image size unless it is a scalable media type.
+In the examples below, the original size of the image is 400 × 267 pixels.
+{|class="wikitable"
+|-
+! Format
+! You type
+! You get
+{{Help:Images/size|frame=}}

+{{Help:Images/size|frame=frameless|note=A <code>frameless</code> image cannot be enlarged beyond the size of the original image.}}
+|}
+==== Horizontal alignment ====
+Note that when using the <code>frame</code> or <code>thumb[nail]</code> formats, the default horizontal alignment will be <code>right</code>.
+{|class="wikitable"
+|-
+!Description
+!You type
+!You get
+<!-- The character sequence &#32; is used below to insert spaces that would otherwise be stripped off the template parameter -->
+{{Help:Images/frame|2=100px|frame=|ex='''no horizontal alignment specified''', or default alignment|inline=yes|float=no|textbefore=text before&#32;|textafter=&#32;text after}}
+{{Help:Images/frame|2=100px|frame=none|ex=specify horizontal alignment as: '''none'''|inline=no|float=no|textbefore=text before&#32;|textafter=&#32;text after}}

+{{Help:Images/frame|2=100px|frame=right|ex=specify horizontal alignment as: '''right'''|inline=no|float=yes|textbefore=text before&#32;|textafter=&#32;text after}}
+|}
+==== Vertical alignment ====
+The vertical alignment options take effect only if the image is displayed as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same row.  Note that the displayed line of text where inline images are inserted (and the lines of text displayed after the current one) may be moved down.  The line spacing will increase, just as may occur with spans of text with variable font sizes to allow the image height to be fully displayed with this alignment constraint.
+To show the alignment result more clearly in this example, the text spans are overlined and underlined, the line-height is increased and emphasized with a yellow background and grey border:

+==== Stopping the text flow ====
+On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image.  Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, <nowiki>== My Header ==</nowiki>) to appear to the right of the image, instead of below it, as a user may expect.  The text flow can be stopped by placing '''<nowiki><br style="clear: both" /></nowiki>''' before the text that should start below the floating image.
+All images displayed as blocks (including non-floating '''center'''ed images, '''left'''- or '''right'''-floating images, as well as '''framed''' or '''thumbnail'''ed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).
+==== Altering the link target ====
+The table below shows how to alter or remove the link target associated with an image.  {{note}}The link attribute '''does not work with''' <code>thumb</code> '''or''' <code>frame</code> formats.
+{|class="wikitable plainlinks"

+=== Displaying an image gallery ===
+It's easy to make a gallery of thumbnails with the <code><nowiki><gallery></nowiki></code> tag:
+ <nowiki><gallery></nowiki>
+ Image:file_name.ext|caption
+ Image:file_name.ext|caption
+ {...}
+ </gallery>
+Note that the image code is not enclosed in quare brackets inside gallery tags. Captions are optional, and may contain wiki links or other formatting.  For example:
+ <nowiki><gallery></nowiki>
+ File:Example.jpg|Item 1
+ File:Example.jpg|a link to <nowiki>[[</nowiki>Help:Contents]]
+ File:Example.jpg
+ File:Example.jpg
+ File:Example.jpg| <nowiki>''italic caption''</nowiki>
+ File:Example.jpg|on page "<nowiki>{{</nowiki>PAGENAME}}"
+ </gallery>
+Is displayed as:
+<gallery>
+File:Example.jpg|Item 1
+File:Example.jpg|a link to [[Help:Contents]]
 File:Example.jpg
 File:Example.jpg
-File:Example.jpg
+File:Example.jpg|''italic caption''
-</gallery>
+File:Example.jpg|on page "{{PAGENAME}}"
+</gallery>
-=== Linking to an image without displaying it ===
+==== Optional gallery attributes ====
-==== Link to description page ====
+The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:
-If you put a colon (<code>:</code>) before <code>{{ns:image}}:</code>, the image will not be embedded and the link will lead to the description page of the file.
+<pre><gallery {parameters}>
+{images}
+</gallery></pre>
+* <code>caption={caption}</code>: A caption for the gallery.
+* <code>widths={width}px</code>: The maximum width for the images. Note the plural (width'''''s''''')
+* <code>heights={heights}px</code>: The maximum height for the images.
+* <code>perrow={integer}</code>: The number of images per row.
+* <code>showfilename={y or n}</code>: Show the filenames in the image captions.
+Example wikitext:
+<pre>
+<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
+File:Example.jpg
+File:Example.jpg

+== Widgets ==
+MediaWiki widgets allow you to embed [[wikipedia:Web widget|web widgets]] into a wiki page.  Each widget has its own documentation, which can be found in the [[Special:AllPages/Widget:|list of available widgets]].
+== Namespaces ==
+Pages in MediaWiki are partitioned into <nowiki>'</nowiki>'''namespaces'''', which indicate the purpose of the pages at a high level.  Namespaces are specified in page titles by prefixing the page name with "<code>namespace:</code>".  For example, the prefix "<code>{{NAMESPACE}}:</code>" in this page's title ("{{FULLPAGENAME}}") indicates that this page is in the {{NAMESPACE}} namespace.
+{{note|Colons and prefixes can also appear in page titles ''without'' indicating a namespace: The page [[Foo:{{PAGENAME}}]] is a page located in the Main namespace, because the namespace "Foo" does not exist.  Similarly the page [[{{NAMESPACE}}:Foo:{{PAGENAME}}]] is in the "{{NAMESPACE}}" namespace.}}
+=== Standard namespaces ===
+These are the namespaces that exist on {{SITENAME}}.  Pages in some namespaces have special properties.
+{| class="wikitable"
+! Namespace
+! Purpose and special properties
+|-
+| {{ns:-2}}
+| An alias used to link directly to media files.
+|- style="border-top:1px solid #666"
+| {{ns:-1}}
+| Used to group [[Special:SpecialPages|special pages]], reports and interfaces that are generated 'on demand' by MediaWiki and which are not directly editable.
+|-
+| Main
+| This namespace typically contains the bulk of the content pages in a wiki. It has no special properties.
+|-
+| {{ns:1}}
+| Used for discussion attached to the main namespace.  It has no special properties.
+|-
+| {{ns:2}}
+| Each user has a corresponding page in the {{ns:2}} namespace, which is linked to from edit histories, watchlists, recent changes, etc; wherever an individual user is uniquely identified. This page, and subpages of it, can be used by users to record information about themselves or to test and draft new content.
+|-
+| {{ns:3}}
+| A discussion space associated with the {{ns:2}} namespace, mainly used to leave messages for particular users or inform them of discussions that may be of interest to them.
+|-
+| {{ns:4}}
+| Normally used for content pages that document the operation and development of the wiki. It has no special properties.
+|-
+| {{ns:5}}
+| Normally used for discussions related to the associated content pages.  It has no special properties.
+|-
+| {{ns:6}}
+| Used to store metadata for images, videos, sound files and other media accessed via the {{ns:-2}} namespace.  Each file has a corresponding page in the {{ns:6}} namespace which is often used to hold licensing data.  Linking ''directly'' to a page in this namespace instead includes the media file inline in the page.  See [[#Images]] for details of the link syntax.  There is an alias "Image" for the {{ns:6}} namespace.
+|-
+| {{ns:7}}
+| Normally used for discussion of the media files.  It has no special properties.
+|-
+| {{ns:8}}
+| Used to hold system messages and other important content.
+|-
+| {{ns:9}}
+| A talk namespace that is normally used for discussions related to the system messages.  It has no special properties.
+|-
+| {{ns:10}}
+| Used to hold [[#Templates|templates]].  To facilitate this it has the special property that it is the ''default'' namespace for transclusions.
+|-
+| {{ns:11}}
+| A talk namespace that is normally used for discussion of the template pages.  It has no special properties.
+|-
+| {{ns:12}}
+| Used to hold help files, instructions and 'how-to' guides.  It has no special properties.
+|-
+| {{ns:13}}
+| Used for discussions related to the help pages.  It has no special properties.
+|-
+| {{ns:14}}
+| Contains [[#Categories|categories]] (dynamic lists of other pages).  To facilitate this, linking ''directly'' to a category page does not output an inline link, but instead adds the page into the associated category page.
+|-
+| {{ns:15}}
+| Used for discussion of the category pages.  It has no special properties.
+|}
+=== Talk pages ===
+The MediaWiki namespaces are organised in pairs, with each pair containing a 'subject namespace' and a 'discussion namespace'.  Every page in a subject namespace has an associated talk page which can be used to communicate with other users. Talk pages can be accessed by clicking the “{{lcfirst:{{int:talk}}}}” tab at the top of a page. Simply edit the page as normal to add your comment.  Also see [[wikipedia:Help:Using talk pages]].
+=== User pages ===
+A '''user page''' in the {{ns:user}} namespace is a page about a member of the wiki.  If you have registered, you can create your own user page. Your user page is linked in the top right. Others will see links to your user page from various places which assist wiki collaboration, including the “{{int:Recentchanges}}” and “{{lcfirst:{{int:history}}}}” pages.  Every user page also has an associated "{{lcfirst:{{ns:3}}}} page". This is a special kind of talk page, for leaving messages directed at a particular user.  Also see [[wikipedia:Wikipedia:User pages|Wikipedia:User pages]].
+=== See also ===
+* To list all the pages in a namespace see [[Special:Allpages]].
+* [[wikipedia:Help:Namespaces]].
+* [[mw:Manual:Namespace]].
+* [[mw:Manual:Using custom namespaces]].
+== Categories ==
+Categories provide a way to automatically index and navigate between related pages.
+=== Adding a page to a category ===
+To add a page to a category, include the following text (where '''''Name''''' is the name of the category).  The usual place to add it is at the bottom of the page.  You can use several of these tags to add a page to multiple categories.
+ <nowiki>[[</nowiki>{{ns:category}}:'''''Name''''']]
+For a complete list of all existing categories see [[Special:Categories]].
+=== Creating a category page ===
+Pages in the '''{{ns:category}}:''' [[#Namespaces|namespace]] contain:
+* a normal body of text that can be edited, like any other page; and
+* an automatically-generated list of the pages in that category.
+If a category is used without creating a 'category page', it will be isolated from others and serve little purpose for organization or navigation.  A category page can be created the same way as other wiki pages (see [[#Starting a new page|starting a new page]]); just add "<code>{{ns:category}}:</code>" before the page title.
+=== Managing the category hierarchy ===
+Categories may belong to other categories in a hierarchy. Since category pages are much like any other page, a {{ns:category}} tag may be added to the bottom of a category page.  It is a good practice to organize all categories into a hierarchy with a single top level category (we use [[:{{ns:Category}}:Root]]).
+For a list of categories that have been used without a category page, see [[Special:WantedCategories]].
+=== Linking to a category ===
+To create a normal wiki link to a category page (without adding your page to the category), prefix the link name with a colon.  For example:
+:<code><nowiki>[[</nowiki>:{{ns:category}}:Help|Help category]]</code> &rarr; '''[[:{{ns:category}}:Help|Help category]]'''
+[[#Redirects|Redirect pages]] that redirect to categories must also use the colon, otherwise they will be added to the category instead of redirecting.
+=== See also ===
+* [[wikipedia:Help:Categories]].
+== Subpages ==
+'''Subpages''' introduce hierarchical organization into wiki pages, with levels of the hierarchy separated by slashes (<code>/</code>).
+=== Where it works ===
+By default, MediaWiki's subpage feature is turned off in the main namespace, but can be used on [[#Talk pages|talk pages]] and [[#User pages|user pages]].  In namespaces where the feature is switched off, any slashes (/) within a page name are simply part of the page name and do nothing special.
+=== How it works ===
+Slashes (/) within a page name break the page into parent and subpages, recursively, e.g.:
+* [[{{NAMESPACE}}:{{PAGENAME}}]] - this page
+* [[{{NAMESPACE}}:{{PAGENAME}}/subpage]] - child page
+* [[{{NAMESPACE}}:{{PAGENAME}}/subpage/sub-subpage]] - grandchild page
+Note that the part of page names after a slash is case sensitive.  In subpages, a link back to the parent page will automatically appear at the top.
+=== Use of subpages ===
+Some typical uses for subpages are:
+* to create archives of old discussions under a [[#Talk pages|talk page]]
+* to create scratchpad editing spaces under a [[#User pages|user page]]
+Subpages are useful for organising information hierarchically. On the other hand, subpages tend to have a long name that is hard to remember, so it may be more user-friendly to use them as little as possible. You can also organize pages with the [[Help:Category|category]] feature, which is more suitable for creating a hierarchical network of information.
+=== See also ===
+* [[wikipedia:Help:Subpages]].
+* [[metawikipedia:Help:Link#Subpage feature]]
+* [[mw:Help:Variables#Page names]]
+* [[Special:PrefixIndex]] &ndash; Provides a list of subpages.
+== Templates ==
+MediaWiki templates can be used to include standard messages on several wiki pages.  If you change a template then the text will be updated on all of the pages where it is used.
+=== Template creation ===
+Templates are standard wiki pages whose content is designed to be [[wikipedia:Transclusion|transcluded]].  You can [[#Starting a new page|create them like any other wiki page]].  Templates follow a convention that the name is prefixed with "<code>Template:</code>".
+=== Using templates ===
+The tag <code><nowiki>{{Name}}</nowiki></code> transcludes the content of a template (stored in the page <nowiki>[[Template:Name]]</nowiki>).  For example, if you have a page called "Template:Welcome" with the contents:
+ Hello! Welcome to the wiki.
+You can insert the code <nowiki>{{Welcome}}</nowiki> in any other page, and when that page is viewed the text "Hello! Welcome to the wiki." will appear.
+An ordinary wiki page can also be used as a template, simply by specifying the full name with the namespace:
+*<code><nowiki>{{:Pagename}}</nowiki></code> includes <code><nowiki>[[Pagename]]</nowiki></code>
+*<code><nowiki>{{Foo:Pagename}}</nowiki></code> includes <code><nowiki>[[Foo:Pagename]]</nowiki></code>
+=== Controlling the time of transclusion ===
+{| class="wikitable"
+! You write
+! Effect
+|-
+| <code><nowiki>{{Name}}</nowiki></code>
+| Transcludes the content of the template (stored in the page <nowiki>[[Template:Name]]</nowiki>) every time the page is fetched and displayed.  If the template is later changed, the transcluding pages will automatically change too.
+|-
+| <code><nowiki>{{msgnw:Name}}</nowiki></code>
+| Includes the template in a form that displays it as raw wiki syntax (the way <code><nowiki>&lt;nowiki&gt;</nowiki></code> does).
+|-
+| <code><nowiki>{{subst:Name}}</nowiki></code>
+| This tag is substituted with the contents of the named template at the time you save the page.  The contents can then be edited separately from the original in the template page. Note: don not use this if you want to continually propagate changes from the source template to the pages that reference it.
+|-
+| <code><nowiki>{{safesubst:Name}}</nowiki></code>
+| A type of substitution that doesn't break transclusion, see [[wikipedia:Help:Substitution#The safesubst: modifier]].
+|}
+=== Parameters ===
+MediaWiki allows parameters to be passed to a template when it is transcluded.  There are three ways to pass parameters: anonymously, by number, and by name.
+To pass in '''anonymous parameters''' to a template, list the values of those parameters sequentially:
+ <nowiki>{{Thankyou|all your effort|Joe}}</nowiki>
+Inside the template these parameters can be accessed by number:
+:<code><nowiki>{{{1}}}</nowiki></code> &rarr; ''all your effort''
+:<code><nowiki>{{{2}}}</nowiki></code> &rarr; ''Joe''
+To pass in parameters ''by number'', identify each parameter when passing it:
+ <nowiki>{{Thankyou|2=Joe|1=all your effort}}</nowiki>
+The third way of passing parameters is '''by name''', instead of numbers.
+ <nowiki>{{Thankyou|signature=Joe|reason=all your effort}}</nowiki>
+Inside the template these parameters can be accessed by name:
+:<code><nowiki>{{{signature}}}</nowiki></code> &rarr; ''Joe''
+:<code><nowiki>{{{reason}}}</nowiki></code> &rarr; ''all your effort''
+The advantage of using named parameters in your template, besides also being flexible in the order parameters can be passed, is that it makes the template code much easier to understand if there are many parameters.
+==== Default values ====
+It is possible to define default values for parameters in case no value is passed in.  The syntax to retrieve a parameter using a default value is:
+ <nowiki>{{{ParameterName|DefaultValue}}}</nowiki>
+The default parameter can be ommitted, in which case it defaults to an empty string:
+ <nowiki>{{{ParameterName|}}}</nowiki>
+=== Control template inclusion ===
+Anything between <code><nowiki><noinclude></nowiki></code> and <code><nowiki></noinclude></nowiki></code> will be displayed only when the template page is viewed directly.
+Possible applications are:
+* Categorising templates
+* Explanatory text about how to use the template.
+To give usage information, include an example like this one on the template page:
+<pre><nowiki>
+<noinclude>
+== Usage ==
+{{Thankyou|reason=your reason|signature=your signature}}
+</noinclude>
+</nowiki></pre>
+The converse is <code><nowiki><includeonly></nowiki></code>. Text between <code><nowiki><includeonly></nowiki></code> and <code><nowiki></includeonly></nowiki></code> will be processed and displayed only when the page is being included. The obvious application is to add all pages containing a given template to a [[#Categories|category]], without putting the template itself into that category.  Notw: When you change the categories applied by a template, the categorization of the pages that use that template may not be updated until some time later.
+=== Organizing templates ===
+For templates to be effective, users need to find them, and find out how to use them.  For a list of all templates, see [[{{ns:special}}:Allpages/Template:]].
+=== See also ===
+* [[mw:Help:Template]] – contains a manual on how templates function
+* [[mw:Help:Embed page]] – embedding pages from [[#Namespaces|namespaces]] other than <code>Template:</code>.
+* [[wikipedia:Help:Templates]]
+== Redirects ==
+Redirects are used to forward users from one page name to another. They can be useful if a particular article is referred to by multiple names, or has alternative punctuation, capitalization or spellings.
+=== Creating a redirect ===
+You may start a new page with the name you want to direct from (see [[#Starting a new page|Starting a new page]]). You can also use an existing page that you are making inactive as a page by going to that page and using the "edit" tab at the top. In either case, insert the following code at the very start of the Edit window for the page:
+ <nowiki>#REDIRECT [[</nowiki>''pagename''<nowiki>]]</nowiki>
+where ''pagename'' is the name of the destination page. There must be no space before the "#" symbol. Any text before the code will disable the code and prevent a redirect.
+=== Double redirects ===
+A double redirect is a page redirecting to a page which is itself a redirect, and it will not work. Instead, people will be presented with a view of the next redirect page. This is a deliberate restriction, partly to prevent infinite loops, and partly to keep things simple.  Double redirects should be eliminated by changing them to be 1-step redirects instead.  Use the "what links here" toolbox link to find double redirects to a particular page, or use [[Special:DoubleRedirects]] to find them throughout the whole wiki.
+=== A redirect to a page in the category namespace ===
+To prevent a page that redirects to a category from appearing in the category, precede the word "Category" with a colon:
+ <nowiki>#REDIRECT [[:Category:Glossary]]</nowiki>
+=== See also ===
+* [[wikipedia:Help:Redirects]]
+== Magic Words ==
+'''Magic words''' are strings of text that MediaWiki interprets as a value or function.  Page-dependent magic words will affect or return data about the ''current'' page (by default), even if the word is added through a transcluded template or included system message.
+=== Behavior switches ===
+A behavior switch controls the layout or behaviour of the page and can often be used to specify desired omissions and inclusions.
+{| class="wikitable"
+|-
+! Word

+|-
+| <code><nowiki>__NOTOC__</nowiki></code>
+| Hides the table of contents (TOC).

+=== Variables ===
+Variables return information about the current page, wiki, or date. Their syntax is similar to templates.
+==== Technical metadata ====
+Revision variables return data about the latest edit to the current page, even if viewing an older version of the page.

+|}
+==== Statistics ====
+Numbers returned by these variables normally contain separators (commas or spaces, depending on the local language), but can return raw numbers with the ":R" flag (for example, <code><nowiki>{{NUMBEROFPAGES}}</nowiki></code> &rarr; {{NUMBEROFPAGES}} and <code><nowiki>{{NUMBEROFPAGES:R}}</nowiki></code> &rarr; {{NUMBEROFPAGES:R}}).

+=== Parser functions ===
+Parser functions have the same syntax as templates.  The names are sometimes prefixed with a hash to distinguish them from template page names.
+==== Conditional expressions ====
+===== #if =====
+This function tests whether the first parameter is non-empty.  It evaluates to false if the test string is empty or contains only whitespace characters (spaces, newlines, etc).
+ <tt><nowiki>{{#if:</nowiki> ''test string'' | ''value if true'' | ''value if false'' <nowiki>}}</nowiki></tt>
+===== #ifeq =====
+This parser function compares two strings and determines whether they are identical.
+ <tt><nowiki>{{#ifeq:</nowiki> ''string 1'' <nowiki>|</nowiki> ''string 2'' <nowiki>|</nowiki> ''value if identical'' <nowiki>|</nowiki> ''value if different'' <nowiki>}}</nowiki></tt>

-results in
+=== Starting a new page ===
+When a link points to an article that doesn't exist yet, the link will be coloured red.  Clicking a red link will take you to the edit page where you can submit the new article.  Usually this is the best way to create a new page, because it means that right from the start the page will be linked from at least one other place on the wiki.  Normally there is no reason to create a page without first creating a red link to it.  An alternative is to search for a page that doesn't exist (using the search box), which will provide a link to create a new stand-alone page.
-[[:{{ns:image}}:{{mediawiki:image_sample}}]]
+=== Copying a page ===
-[[:{{ns:image}}:{{mediawiki:image_sample}}|Sunflowers]]
+There is no facility to copy a page in MediaWiki, so you must copy and paste the wikitext.  It is not possible to copy the edit history from one page to another.
-==== Link to another page ====
+=== Moving (renaming) a page ===
-{{note|link '''does not work with''' thumb '''or''' frame.}}
+The name of a page can be changed by using the "{{lc:{{MediaWiki:move}}}}" tab at the top. This tab is only visible if you are logged in.  By using this feature, you also move the editing history of the page, which allows people to see how the contents of the page were built up, and who contributed what.  Because the move operation leaves behind a redirect (see [[#Redirects|Redirects]]), it should not result in any broken links, however you might want to find pages which link to the old title, and change their text to link directly to the new title (see [[#Unlinking a page|Unlinking a page]]).
-This will make a 50px width picture with a link to the page [[MediaWiki]]:
- <nowiki>[[</nowiki>File:Wiki.png|50px|link=MediaWiki]]
+Deciding on a page title can be a difficult aspect of wiki organization, and one which can provoke debates. If the move could be considered controversial, you should propose the move first (see [[{{ns:Project}}:Propose a page move]]).
-[[File:Wiki.png|50px|link=MediaWiki]]
+As with all wiki editing, a move operation can be reversed.  To reverse a move operation, simply move the page back to the previous name.  If a page is renamed from "A" to "B" and then back to "A", a page with the title "B" will still be left behind, as a redirect from "B" to "A".  To remove this page see [[#Deleting a page|deleting a page]]).  Alternatively, users with the <code>suppressredirect</code> [[mw:Help:User rights|permission]] will see the option to move a page without creating a redirect.
-==== Link directly to the media file ====
+=== Deleting a page ===
-You can use the pseudo-namespace “{{ns:media}}” to link directly to a file without rendering it, bypassing the description page.
+Normal users cannot permanently delete a wiki page. This is a deliberate design feature; every kind of editing operation can be reverted and that includes resurrecting deleted pages. If for some reason you need a page to be deleted urgently, please see [[{{ns:Project}}:Mark a page for deletion]].  For any other deletion that might be controversial or disruptive, you should propose the change first (see [[{{ns:Project}}:Propose a page deletion]]).

-You can also use:&nbsp;
- <nowiki>[[</nowiki>{{#special:Filepath}}/{{mediawiki:image_sample}}]]
-which can be used to link to a potential file, even if it doesn't exist. You can also use:
-  <nowiki>{{</nowiki>FILEPATH:{{mediawiki:image_sample}}<nowiki>}}</nowiki>
-which generates an external URL to the file inline: {{FILEPATH:{{mediawiki:image_sample}}}}
-=== Files at other websites ===
-You can link to an external file available online using the same syntax used for linking to an external web page.  With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.
-<pre>[http://url.for/some/image.png]</pre>
-Or with a different displayed text:
-<pre>[http://url.for/some/image.png link text here]</pre>
-Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):
-<pre>[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]</pre>
-which renders as: [http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text<ins>'' here.]
-If it is enabled on your wiki (see {{mediawiki|Manual:$wgAllowExternalImages}}), you can also embed external images. To do that, simply insert the image's url:
-<pre>http://url.for/some/image.png</pre>
-Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.
-If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.

+==== Unlinking a page ====
+The "{{MediaWiki:whatlinkshere}}" feature in the {{MediaWiki:toolbox}} (at the bottom of the [[mw:Help:Navigation#Sidebar|sidebar]]) will tell you which other Wiki pages link to the current page. Always use this feature to check before deleting a page. These related pages will need to be edited for their links to reflect the change.
-== Wishlist ==
+== System Information ==
-This is a list of extensions and changes that would improve Nottinghack's MediaWiki.  These extensions are very stable and widely used:
-==== Critical ====
+{{SITENAME}} is running MediaWiki <code>{{CURRENTVERSION}}</code>.  See:
-* Install [http://www.mediawiki.org/wiki/Extension:ParserFunctions ParserFunctions].  These are really useful, and without them you can only create very basic templates.  I would like to use them to get the templates to work on this page.
+* Detailed [[{{#Special:Version}}|version information and the list of extensions]]
+* The [[{{ns:Special}}:Interwiki|Interwiki Table]]
+* [[{{ns:Special}}:Statistics|Usage statistics]]
+* The [[{{ns:Special}}:NewFiles|gallery]] or [[{{ns:Special}}:ListFiles|list]] of recently uploaded files.
+* [[{{ns:Special}}:NewFiles|Unused files]] that might not be needed.
+* Other [[{{ns:Special}}:SpecialPages|SpecialPages]]
-==== Essential ====
+== See also ==
-Every tech wiki needs these:
-* Enable the <code>&lt;math&gt;</code> features built into MediaWiki (See [http://www.mediawiki.org/wiki/Manual:Enable_TeX]), so we can display formulae.
-* The [http://www.mediawiki.org/wiki/Extension:SyntaxHighlight_GeSHi SyntaxHighlight GeSHi] extension for code samples.
-==== Desirables ====
+* A [[wikipedia:Help:Wiki markup|shorter wiki markup reference]] on Wikipedia.
-* The &lt;poem&gt; extension makes it possible to write poem-like text without a mass of &lt;br /&gt; tags.
-* If possible, an extension to display the Interwiki map - at the moment we have to guess.
-* The [http://www.mediawiki.org/wiki/Extension:WikiWidgets widgets extention] would let us embed maps, youtube videos, the flickr gallery, etc.
-* Inline SVG support, so we can display diagrams.  Even better would be an inline SVG editor, so we can collaborate on them.
