'''Editing''' a Wiki page is very easy. Simply click on the "'''edit'''" tab at the top (or the edit link on the right or bottom) of a Wiki page. This will bring you to a page with a text box containing the editable text of that page. '''If you just want to experiment, please do so in the [[Sandbox]] or (preferably) in your own user area'''; not here. You should write a short [[Wikipedia:Edit summary|edit summary]] in the small field below the edit-box. You may use shorthand to describe your changes, as described in the [[Wikipedia:Edit summary legend|legend]], and when you have finished, press [[Wikipedia:Show preview|preview]] to see how your changes will look. You can also see what changes you have made in comparison to the previous version by pressing the [[Wikipedia:Show changes|Show changes]] button. If you're happy with what you see, then press "Save" and your changes will be immediately applied to the article.  Don't "sign" edits you make to regular articles (the software keeps track of who makes every change).
  
This guide is by no means extensive in any way, so refer to [http://en.wikipedia.org/wiki/Wikipedia:How_to_edit_a_page the wikipedia documentation] for more authoritative information!

== Tips on editing Wikipedia articles ==
  
==Wikifying Text==
+
Always use a [[neutral point of view]], as Wikipedia is not a place to promote points of view.
  
===Article Links===
+
[[Wikipedia:Cite your sources|Cite your sources]] so others can check and extend your work. Most Wikipedia articles currently lack good references, and this contributes to Wikipedia's single greatest criticism—that it is not a reliable source.  Please help by researching online and print resources to find references for the article you are working on, then cite them in proper form, and consider in-text citation for contentious facts.  There is no consensus on the best way to do that, but anything is better than nothing.  You can either use in-text citation in academic form such as (Example, 2004, pp 22-23) or as a superscript<sup>[[Wikipedia:WikiProject Fact and Reference Check|1]]</sup> to a footnote that you place at the end of an article.
  
To wikify some text (or make it a "wiki word"), wrap it in double square brackets <nowiki>[[thusly]]</nowiki> &mdash; this would lead to the word "thusly" becoming a link within the page.  Clicking on the link would either take you to the article called "thusly" (if it exists), or to an edit page to create a "thusly" article. Being able to 'tag' any such text and make it a link to an article, existing or not, is one of the strengths of the wiki system &mdash; most traditional wikis simply tag any text WhichIsInterCappedWithoutSpaces.  MediaWiki allows ''any'' text to be tagged using the square bracket encapsulation, and leads to a more readable form of wiki word.
+
After making a new page, it's a good idea to:
 +
* Create at least one link from another page. Pages with no links are referred to as '''orphans''' and are officially discouraged.
 +
* Assign the page to at least one category. A [http://www.mediawiki.org/wiki/Help:Categories Category] is a logical grouping of pages that discuss a common theme or topic. Assigning a page to more than one category is encouraged.
  
''Example:'' This document will contain <nowiki>[[terms and conditions]]</nowiki> which will need to be confirmed by the <nowiki>[[customer]]</nowiki> via our website.<br />
+
== Minor edits ==
''Output:'' This document will contain [[terms and conditions]] which will need to be confirmed by the [[customer]] via our website.
+
''See also [[Wikipedia:Minor edit]]''
  
You can alter the rendered output of a wiki word link by placing a pipe symbol &mdash; | &mdash; after the word(s) then enter the text you wish to be displayed.
+
When editing a page, a [[Wikipedia:How to log in|logged-in]] user can mark that edit as being "minor". Minor edits generally mean spelling corrections, formatting, and minor rearrangement of text. It is possible to ''hide'' minor edits when viewing [[Wikipedia:Recent Changes]]. Marking a significant change as a minor edit is considered bad behavior, and even more so if it involves the deletion of some text. If one has accidentally marked an edit as minor, the person should edit the source once more, mark it major (or, rather, ensure that the check-box for "This is a minor edit" is not checked), and, in the summary, state that the previous change was a major one.
  
''Example:'' This document could contain <nowiki>[[privacy statement|our privacy statement]]</nowiki>.<br />
+
== Wiki markup ==
''Output:'' This document could contain [[privacy statement|our privacy statement]].
 
  
===Outside Links===
+
The '''wiki markup''' is the syntax system you can use to format a Wikipedia page.
  
To have a URL linking to an external site, simply enter the URL into the article text; it will be automatically hyperlinked by MediaWiki.
+
In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.
  
''Example:'' <nowiki>http://www.some.site/path/to/document</nowiki><br />
+
You may want to keep this page open in a separate browser window for reference, or take a screen-shot of it. '''If you want to try out things without danger of doing any harm, you can do so in the [[Wikipedia:Sandbox|Sandbox]] or (preferably) in your own user area'''. Try opening the Sandbox in a separate window or tab and keeping this page open for reference.
''Output:'' http://www.some.site/path/to/document
 
  
To hyperlink some text, as you would with <nowiki><a href></nowiki>, encapsulate the URL and your link text in single square brackets, URL first and your text delimited by a space.

 +
-->
 +
'''<font style="font-size:120%">New section</font>'''
  
To present a hyperlink in a similar form to a footnote, encapsulate the URL alone in single square brackets with no spaces or additional text.  The hyperlink will be shown inside square brackets with a number &mdash; the number shown will depend on how many previous hyperlinks have been entered in this way.
+
'''<font style="font-size:110%">Subsection</font>'''
  
''Example:'' <nowiki>[http://www.some.site/path/to/document]</nowiki> <nowiki>[http://www.another.site/path/on/the/site]</nowiki><br />

'''<font style="font-size:100%">Sub-subsection</font>'''
''Output:'' [http://www.some.site/path/to/document] [http://another.site/path/on/the/site]
 
  
===Embedding External Graphics===
+
* Start with a second-level heading (<tt><nowiki>==</nowiki></tt>); don't use first-level headings (=).
 +
* Don't skip levels (for example, second-level followed by fourth-level).
 +
* A [[#Placement_of_the_Table_of_Contents_.28TOC.29|Table of Contents]] will automatically be added to an article that has four or more sections.
 +
*If appropriate, place subsections in an appropriate order. If listing countries, place them in alphabetical order rather than, say, relative to population of [[OECD]] countries, or some random order.

To show output from an email, code or other fixed-width character text, you can show this text in a similar fashion to <nowiki><pre></nowiki>, simply by using the <nowiki><pre></pre></nowiki> tags as normal, or adding a space to the start of each line of text.  Unfortunately, due to the way the HTML will be rendered from this article, you'll have to take the latter as a matter of faith, but we can demonstrate the use of <nowiki><pre></nowiki>.

===Miscellany===
+
* A link to another Wikipedia article.
 +
* Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
 +
* Thus the link above is to the [[URL]] www.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also [[Wikipedia:Canonicalization]].

Other formatting can be used, such as <nowiki><br /></nowiki> tags to create a line break where necessary. A single line break after text will not result in the intended effect &mdash; either use <nowiki><br /></nowiki> with the actual line break in text (for readability's sake) or insert a second line break to start a new paragraph (akin to <nowiki><p></nowiki>).

* Same target, different name.

Three ways to link to external (non-wiki) sources:
 +
# Bare URL: http://www.nupedia.com/ (bad style)
 +
# Unnamed link: [http://www.nupedia.com/] (only used within article body for footnotes)
 +
# Named link: [http://www.nupedia.com Nupedia]
 +
 
 +
:See [[MetaWikiPedia:Interwiki_map]] for the list of shortcuts.
 +
 
 +
* Square brackets indicate an external link. Note the use of a ''space'' (not a pipe) to separate the URL from the link text in the "named" version.
 +
* In the [[URL]], all symbols must be among:<br/>'''A-Z a-z 0-9 . _ \ / ~ % - + &amp; # ? ! = ( ) @ \x80-\xFF'''
 +
* If a URL contains a character not in this list, it should be encoded by using a percent sign (%) followed by the [[hexadecimal|hex]] code of the character, which can be found in the table of [[ASCII#ASCII printable characters|ASCII printable characters]]. For example, the caret character (^) would be encoded in a URL as '''%5E'''.
 +
* There is a class that can be used to remove the arrow image from the external link. It is used in [[Template:Ref]] to stop the URL from expanding during printing. It should '''never''' be used in the main body of an article. However, there is an exception: wikilinks in Image markup. An example of the markup is as follows:
 +
** Markup: <nowiki><span class="plainlinksneverexpand"> [http://www.sysinternals.com/ntw2k/freeware/winobj.shtml WinObj]</span></nowiki>
 +
** Display: <span class="plainlinksneverexpand"> [http://www.sysinternals.com/ntw2k/freeware/winobj.shtml WinObj] </span>

* See [[Wikipedia:External links]] for style issues.

=== Embedded Video ===
 +
 
 +
Video clips that are hosted on other video sharing services, such as Google Video, YouTube, and Vimeo may be embedded in wiki pages.
 +
 
 +
From the [http://www.mediawiki.org/wiki/Extension:EmbedVideo EmbedVideo] article at MediaWiki.org:
 +
 
 +
The EmbedVideo parser function expects to be called in any of the following ways:
 +
* <tt><nowiki>{{#ev:service|id}}</nowiki></tt>
 +
* <tt><nowiki>{{#ev:service|id|width}}</nowiki></tt>
 +
* <tt><nowiki>{{#ev:service|id|width|align}}</nowiki></tt>
 +
* <tt><nowiki>{{#ev:service|id|width|align|desc}}</nowiki></tt>
 +
* <tt><nowiki>{{#evp:service|id|desc}}</nowiki></tt>
 +
* <tt><nowiki>{{#evp:service|id|desc|align}}</nowiki></tt>
 +
* <tt><nowiki>{{#evp:service|id|desc|align|width}}</nowiki></tt>
 +
 
 +
Where:
 +
* <tt>service</tt> is the name of a video sharing service (See "service name" in the list below)
 +
* <tt>id</tt> is the id of the video to include
 +
* <tt>width</tt> (optional) is the width in pixels of the viewing area (height will be determined automatically)
 +
* <tt>align</tt> (optional) is an alignment (float) attribute. May be "left" or "right".
 +
* <tt>desc</tt> (optional) is a short description to display beneath the video when it is aligned
 +
 
 +
For example, to include the famous "evolution of dance" YouTube video, you'd enter:
 +
<pre>{{#ev:youtube|dMH0bHeiRNg}}</pre>
 +
 
 +
And if you wanted scaled down to thumbnail size, on the right with a short description, you could use:
 +
<pre>{{#ev:youtube|dMH0bHeiRNg|100|right|This is an embedded video!}}</pre>
 +
 
 +
:''Note: See the [http://wiki.github.com/Whiteknight/mediawiki-embedvideo/ Project Homepage] for more examples.''

Ordinary text should use [[#emph|wiki markup for emphasis]], and should not use <code>&lt;i&gt;</code> or <code>&lt;b&gt;</code>.  However, mathematical formulas often use italics, and sometimes use bold, for reasons unrelated to emphasis.  Complex formulas should use [[Help:Formula|<code>&lt;math&gt;</code> markup]], and simple formulas may use <code>&lt;math&gt;</code>; or <code>&lt;i&gt;</code> and <code>&lt;b&gt;</code>; or <code><nowiki>''</nowiki></code> and <code><nowiki>'''</nowiki></code>.  According to [[Wikipedia:WikiProject Mathematics#Italicization and bolding|WikiProject Mathematics]], wiki markup is preferred over HTML markup like <code>&lt;i&gt;</code> and <code>&lt;b&gt;</code>.

=== Table of Contents ===
 +
<!-- ==== Placement of the Table of Contents (TOC) ==== -->
 +
At the current status of the wiki markup language, having at least four headers on a page triggers the TOC to appear in front of the first header (or after introductory sections).  Putting <nowiki>__TOC__</nowiki> anywhere forces the TOC to appear at that point (instead of just before the first header).  Putting <nowiki>__NOTOC__</nowiki> anywhere forces the TOC to disappear.  See also [[Wikipedia:Section#Compact_TOC|compact TOC]] for alphabet and year headings.
 +
<!--
 +
THE TEXT BELOW IS COMMENTED OUT SINCE THE DESCRIBED TECHNIQUE
 +
DOESN'T WORK AFTER UPGRADING TO MEDIAWIKI 1.5
 +
 
 +
==== Keeping headings out of the Table of Contents ====
 +
 
 +
If you want some subheadings to not appear in the Table of Contents, then make the following replacements.
 +
 
 +
Replace  <nowiki> == Header 2 == with <h2> Header 2 </h2> </nowiki>
 +
 
 +
Replace  <nowiki> === Header 3 === with <h3> Header 3 </h3> </nowiki>
 +
 
 +
And so forth.
 +
 
 +
For example, notice that the following header has the same font as the other subheaders to this "Tables" section, but the following header does not appear in the Table of Contents for this page.
 +
 
 +
<h4> This header has the h4 font, but is NOT in the Table of Contents (actually, it is)</h4>
 +
 
 +
This effect is obtained by the following line of code.
 +
 
 +
<code><nowiki><h4> This header has the h4 font, but is NOT in the Table of Contents </h4></nowiki></code>
 +
 
 +
Note that when editing by section, this approach places the text between the tags in the subsequent section, not the previous section. To edit this text, click the edit link next to "Tables", not the one above.
 +
-->
 +
 
 +
=== Tables ===
 +
There are two ways to build tables:
 +
*in special Wiki-markup (see [http://www.mediawiki.org/wiki/Simplified_table_syntax Syntax])
 +

'''NUMBEROFARTICLES''' is the number of pages in the main namespace which contain a link and are not a redirect, in other words number of articles, stubs containing a link, and disambiguation pages.
 +
 
 +
'''CURRENTMONTHNAMEGEN''' is the genitive (possessive) grammatical form of the month name, as used in some languages; '''CURRENTMONTHNAME''' is the nominative (subject) form, as usually seen in English.
 +
 
 +
In languages where it makes a difference, you can use constructs like <nowiki>{{grammar:case|word}}</nowiki> to convert a word from the nominative case to some other caseFor example, <nowiki>{{grammar:genitive|{{CURRENTMONTHNAME}}}}</nowiki> means the same as <nowiki>{{CURRENTMONTHNAMEGEN}}</nowiki>. <!-- Is there a reference for this, other than the source code (for example, phase3/languages/Lnaguage*.php) ? -->
 +
 
 +
===Templates===
 +
 
 +
The [[Wikipedia:MediaWiki|MediaWiki]] software used by Wikipedia has support for templates. This means standardized text chunks (such as [[Wikipedia:Template messages|boilerplate]] text) can be inserted into articles. For example, typing <nowiki>{{stub}}</nowiki> will appear as "''This article is a [[Wikipedia:Stub|stub]]. You can help Wikipedia by [[Wikipedia:Stub|expanding it]].''" when the page is saved. See [[Wikipedia:Template messages]] for the complete list. Other commonly used templates are: <nowiki>{{disambig}}</nowiki> for disambiguation pages, <nowiki>{{spoiler}}</nowiki> for spoiler warnings and <nowiki>{{sectstub}}</nowiki> like an article stub but for a section. There are many subject-specific stubs for example: <nowiki> {{Geo-stub}}, {{Hist-stub}}, and {{Linux-stub}}</nowiki>. For a complete list of stubs see [[WP:WSS/ST]].
 +
 
 +
===Hiding the edit links===
 +
 
 +
Insert '''<nowiki>__NOEDITSECTION__</nowiki>''' into the document to suppress the edit links that appear next to every section header.

Latest revision as of 17:52, 2 February 2016

Editing a Wiki page is very easy. Simply click on the "edit" tab at the top (or the edit link on the right or bottom) of a Wiki page. This will bring you to a page with a text box containing the editable text of that page. If you just want to experiment, please do so in the Sandbox or (preferably) in your own user area; not here. You should write a short edit summary in the small field below the edit-box. You may use shorthand to describe your changes, as described in the legend, and when you have finished, press preview to see how your changes will look. You can also see what changes you have made in comparison to the previous version by pressing the Show changes button. If you're happy with what you see, then press "Save" and your changes will be immediately applied to the article. Don't "sign" edits you make to regular articles (the software keeps track of who makes every change).

Please use the Wiki forum at RadioReference to discuss content, themes, fixes or other topics regarding articles on this site.

Tips on editing Wikipedia articles

Always use a neutral point of view, as Wikipedia is not a place to promote points of view.

Cite your sources so others can check and extend your work. Most Wikipedia articles currently lack good references, and this contributes to Wikipedia's single greatest criticism—that it is not a reliable source. Please help by researching online and print resources to find references for the article you are working on, then cite them in proper form, and consider in-text citation for contentious facts. There is no consensus on the best way to do that, but anything is better than nothing. You can either use in-text citation in academic form such as (Example, 2004, pp 22-23) or as a superscript1 to a footnote that you place at the end of an article.

After making a new page, it's a good idea to:

  • Create at least one link from another page. Pages with no links are referred to as orphans and are officially discouraged.
  • Assign the page to at least one category. A Category is a logical grouping of pages that discuss a common theme or topic. Assigning a page to more than one category is encouraged.

Minor edits

See also Wikipedia:Minor edit

When editing a page, a logged-in user can mark that edit as being "minor". Minor edits generally mean spelling corrections, formatting, and minor rearrangement of text. It is possible to hide minor edits when viewing Wikipedia:Recent Changes. Marking a significant change as a minor edit is considered bad behavior, and even more so if it involves the deletion of some text. If one has accidentally marked an edit as minor, the person should edit the source once more, mark it major (or, rather, ensure that the check-box for "This is a minor edit" is not checked), and, in the summary, state that the previous change was a major one.

Wiki markup

The wiki markup is the syntax system you can use to format a Wikipedia page.

In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

You may want to keep this page open in a separate browser window for reference, or take a screen-shot of it. If you want to try out things without danger of doing any harm, you can do so in the Sandbox or (preferably) in your own user area. Try opening the Sandbox in a separate window or tab and keeping this page open for reference.


What it looks like What you type

Start your sections as follows:

New section

Subsection

Sub-subsection

  • Start with a second-level heading (==); don't use first-level headings (=).
  • Don't skip levels (for example, second-level followed by fourth-level).
  • A Table of Contents will automatically be added to an article that has four or more sections.
  • If appropriate, place subsections in an appropriate order. If listing countries, place them in alphabetical order rather than, say, relative to population of OECD countries, or some random order.
== New section ==

=== Subsection ===

==== Sub-subsection ====

A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the function diff (used internally to compare different versions of a page).

But an empty line starts a new paragraph.

  • When used in a list, a newline does affect the layout (see below).

These can be used to separate
sentences within a paragraph.
Some editors find that this aids editing
and improves the function ''diff'' 
(used internally to compare

But an empty line

You can break lines
without starting a new paragraph.

  • Please use this sparingly.
  • Close markup between lines, do not start a link or italics or bold on one line and close it on the next.
You can break lines<br/>
without starting a new paragraph.
  • It's easy to create a list:
    • Start every line with a star (= asterisk).
      • More stars means deeper levels.
        • A newline in a list

marks the end of a list item.

  • An empty line starts a new list.
* It's easy to create a list:
** Start every line with a star.
*** More stars means deeper levels.
**** A newline in a list
marks the end of a list item.

    1. very organized
    2. easy to follow

  • You can even create mixed lists
    1. and nest them
      • like this
* You can even create mixed lists
*# and nest them
*#* like this
Definition list 
list of definitions
item 
the item's definition
another item
the other item's definition
  • One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.
; Definition list : list of definitions
; item : the item's definition
; another item
: the other item's definition
A colon indents a line or paragraph.

A manual newline starts a new paragraph.

  • This is primarily for displayed material, but is also used for discussion on Talk pages.
: A colon indents a line or paragraph.
A manual newline starts a new paragraph.

When there is a need for separating a block of text

the blockquote command will indent both margins when needed instead of the left margin only as the colon does.

This is useful for (as the name says) inserting blocks of quoted (and cited) text.

<blockquote>
The '''blockquote''' command will indent 
both margins when needed instead of the 
left margin only as the colon does.  
</blockquote>
IF a line starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines will not wrap;
ENDIF
  • This is useful for:
    • pasting preformatted text;
    • algorithm descriptions;
    • program source code;
    • ASCII art;
    • chemical structures;
  • WARNING: If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.
 IF a line starts with a space THEN
 it will be formatted exactly

 lines will not wrap;
 ENDIF
Centered text.
  • Please note the American spelling of "center."
<center>Centered text.</center>

A horizontal dividing line: this is above it


and this is below it.

  • Mainly useful for
    • disambiguation - but to be used sparsely, only when separating completely different, unrelated (groups of) meanings
    • separating threads on Talk pages.
A [[horizontal dividing line]]:
this is above it
----
and this is below it.

Links and URLs

What it looks like What you type

London has public transport.

  • A link to another Wikipedia article.
  • Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
  • Thus the link above is to the URL www.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Wikipedia:Canonicalization.
London has [[public transport]].

San Francisco also has public transportation.

  • Same target, different name.
  • This is a piped link.
  • The "piped" text must be placed first, the text that will be displayed, second.
San Francisco also has
[[public transport|public transportation]].

San Francisco also has public transportation.

Examples include buses, taxis, and streetcars.

  • Endings are blended into the link.
  • Preferred style is to use this instead of a piped link, if possible.
San Francisco also has
[[public transport]]ation.

Examples include [[bus]]es, [[taxi]]s,
and [[streetcar]]s.

See the Wikipedia:Manual of Style.

See the [[Wikipedia:Manual of Style]].

Automatically hide stuff in parentheses: kingdom.

Automatically hide namespace: Village Pump.

Or both: Manual of Style

But not: [[Wikipedia:Manual of Style#Links|]]

  • The server fills in the part after the pipe character (|) when you save the page. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page (see previous entry).
Automatically hide stuff in parentheses:
[[kingdom (biology)|]].

Automatically hide namespace: 
[[Wikipedia:Village Pump|]].

Or both:
[[Wikipedia:Manual of Style (headings)|]]

But not:
[[Wikipedia:Manual of Style#Links|]]

The weather in London is a page that does not exist yet.

  • You can create it by clicking on the link (but please do not do so with this particular link).
  • To create a new page:
    1. Create a link to it on some other (related) page.
    2. Save that page.
    3. Click on the link you just made. The new page will open for editing.
  • For more information, see How to start a page and check out Wikipedia's naming conventions.
  • Please do not create a new article without linking to it from at least one other article.
[[The weather in London]] is a page 
that does not exist yet.

Wikipedia:How to edit a page is this page.

  • Self links appear as bold text when the article is viewed.
  • Do not use this technique to make the article name bold in the first paragraph; see the Manual of Style.
[[Wikipedia:How to edit a page]] is this page.

When adding a comment to a Talk page, you should sign it by adding three tildes to add your user name:

Ben Brockert

or four to add user name plus date/time:

Ben Brockert 00:18, Nov 19, 2004 (UTC)

Five tildes gives the date/time alone:

00:18, Nov 19, 2004 (UTC)
  • The first two both provide a link to your user page.
When adding a comment to a Talk page,
you should sign it by adding
three tildes to add your user name:
: ~~~
or four for user name plus date/time:
: ~~~~
Five tildes gives the date/time alone:
: ~~~~~
  • Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").
  • Note that, while it is possible to link to a section, it is not possible to redirect to a section. For example, "#REDIRECT [[United States#History]]" will redirect to the United States page, but not to any particular section on it. This feature will not be implemented in the future, so such redirects should not be used.
#REDIRECT [[United States]]
  • Link to a page on the same subject in another language by using a link of the form: [[language code:Title]].
  • It does not matter where you put these links while editing as they will always show up in the same place when you save the page, but placement at the end of the edit box is recommended.
  • Please see Wikipedia:Interlanguage links and the list of languages and codes.
[[fr:Wikipédia:Aide]]

What links here and Related changes pages can be linked as: Special:Whatlinkshere/Wikipedia:How to edit a page and Special:Recentchangeslinked/Wikipedia:How to edit a page

  • To put an article in a Wikipedia:Category, place a link like the one to the right anywhere in the article. As with interlanguage links, it does not matter where you put these links while editing as they will always show up in the same place when you save the page, but placement at the end of the edit box is recommended.

Embedded Video

Video clips that are hosted on other video sharing services, such as Google Video, YouTube, and Vimeo may be embedded in wiki pages.

From the EmbedVideo article at MediaWiki.org:

The EmbedVideo parser function expects to be called in any of the following ways:

  • {{#ev:service|id}}
  • {{#ev:service|id|width}}
  • {{#ev:service|id|width|align}}
  • {{#ev:service|id|width|align|desc}}
  • {{#evp:service|id|desc}}
  • {{#evp:service|id|desc|align}}
  • {{#evp:service|id|desc|align|width}}

Where:

  • service is the name of a video sharing service (See "service name" in the list below)
  • id is the id of the video to include
  • width (optional) is the width in pixels of the viewing area (height will be determined automatically)
  • align (optional) is an alignment (float) attribute. May be "left" or "right".
  • desc (optional) is a short description to display beneath the video when it is aligned

For example, to include the famous "evolution of dance" YouTube video, you'd enter:

{{#ev:youtube|dMH0bHeiRNg}}

And if you wanted scaled down to thumbnail size, on the right with a short description, you could use:

{{#ev:youtube|dMH0bHeiRNg|100|right|This is an embedded video!}}
Note: See the Project Homepage for more examples.

Character formatting

What it looks like What you type

Emphasize, strongly, very strongly.

  • These are double, triple, and quintuple apostrophes (single-quote marks), not double-quote marks.
''Emphasize'', '''strongly''', '''''very strongly'''''.

<math>\sin x + \ln y</math>
sinx + lny

<math>\mathbf{x} = 0</math>
x = 0

Ordinary text should use wiki markup for emphasis, and should not use <i> or <b>. However, mathematical formulas often use italics, and sometimes use bold, for reasons unrelated to emphasis. Complex formulas should use <math> markup, and simple formulas may use <math>; or <i> and <b>; or '' and '''. According to WikiProject Mathematics, wiki markup is preferred over HTML markup like <i> and <b>.

<math>\sin x + \ln y</math>
sin''x'' + ln''y''

<math>\mathbf{x} = 0</math>
'''x''' = 0

A typewriter font for monospace text or for computer code: int main()

  • For semantic reasons, using <code> where applicable is preferable to using <tt>.
A typewriter font for <tt>monospace text</tt>
or for computer code: <code>int main()</code>

You can use small text for captions.

You can use <small>small text</small> for captions.

You can strike out deleted material and underline new material.

You can also mark deleted material and inserted material using logical markup rather than visual markup.

  • When editing regular Wikipedia articles, just make your changes and do not mark them up in any special way.
  • When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted material.
You can <s>strike out deleted material</s>
and <u>underline new material</u>.

You can also mark <del>deleted material</del> and
<ins>inserted material</ins> using logical markup
rather than visual markup.

  • The latter methods of sub/superscripting cannot be used in the most general context, as they rely on Unicode support which may not be present on all users' machines. For the 1-2-3 superscripts, it is nevertheless preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

Spacing in simple math formulas:
Obviously, x² ≥ 0 is true.

  • To space things out without allowing line breaks to interrupt the formula, use non-breaking spaces: &nbsp;.


Obviously, ''x''&sup2;&nbsp;&ge;&nbsp;0 is true.

Complicated formulas:

<math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>
  • See Help:Formula for how to use <math>.
  • A formula displayed on a line by itself should probably be indented by using the colon (:) character.


: <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>

Suppressing interpretation of markup:
Link → (''to'') the [[Wikipedia FAQ]]

  • Used to show literal data that would otherwise have special meaning.
  • Escape all wiki markup, including that which looks like HTML tags.
  • Does not escape HTML character references.
  • To escape HTML character references such as &rarr; use &amp;rarr;


<nowiki>Link &rarr; (''to'') 
the [[Wikipedia FAQ]]</nowiki>

Commenting page source:
not shown when viewing page

  • Used to leave comments in a page for future editors.
  • Note that most comments should go on the appropriate Talk page.

Table of Contents

At the current status of the wiki markup language, having at least four headers on a page triggers the TOC to appear in front of the first header (or after introductory sections). Putting __TOC__ anywhere forces the TOC to appear at that point (instead of just before the first header). Putting __NOTOC__ anywhere forces the TOC to disappear. See also compact TOC for alphabet and year headings.

Tables

There are two ways to build tables:

  • in special Wiki-markup (see Syntax)
  • with the usual HTML elements: <table>, <tr>, <td> or <th>.

More information can be found in the MediaWiki Table Help article.

NUMBEROFARTICLES is the number of pages in the main namespace which contain a link and are not a redirect, in other words number of articles, stubs containing a link, and disambiguation pages.

CURRENTMONTHNAMEGEN is the genitive (possessive) grammatical form of the month name, as used in some languages; CURRENTMONTHNAME is the nominative (subject) form, as usually seen in English.

In languages where it makes a difference, you can use constructs like {{grammar:case|word}} to convert a word from the nominative case to some other case. For example, {{grammar:genitive|{{CURRENTMONTHNAME}}}} means the same as {{CURRENTMONTHNAMEGEN}}.

Templates

The MediaWiki software used by Wikipedia has support for templates. This means standardized text chunks (such as boilerplate text) can be inserted into articles. For example, typing {{stub}} will appear as "This article is a stub. You can help Wikipedia by expanding it." when the page is saved. See Wikipedia:Template messages for the complete list. Other commonly used templates are: {{disambig}} for disambiguation pages, {{spoiler}} for spoiler warnings and {{sectstub}} like an article stub but for a section. There are many subject-specific stubs for example: {{Geo-stub}}, {{Hist-stub}}, and {{Linux-stub}}. For a complete list of stubs see WP:WSS/ST.

Hiding the edit links

Insert __NOEDITSECTION__ into the document to suppress the edit links that appear next to every section header.
