[[Wikipedia]] is a [[wiki]] and this means anyone can easily edit any [[Wikipedia:Protected page|unprotected page]] and save those changes immediately to that page. After your first edit, you will be a Wikipedia editor! <!-- Comment Good luck with your first edit. -->
 +
===Introduction===
 +
<div class="messagebox" style="float: right; width: 150px; margin-left: 10px;">Note: You can use the [[Wikipedia:Sandbox|sandbox]] to experiment with page editing.</div>
 +
Editing most Wikipedia pages is not difficult. Simply click on the "'''edit this page'''" tab at the top of a Wikipedia page (or on a [[Wikipedia: Section | section-edit]] link). This will bring you to a new page with a text box containing the editable text of the original page.  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 see the difference between the page with your edits and the previous version of the page by pressing the "'''Show changes'''" button. If you're satisfied with what you see, [[Wikipedia:Be_bold_in_updating_pages | be bold]] and press the "'''Save page'''" button. Your changes will immediately be visible to all Wikipedia users.

+
You can also click on the "'''Discussion'''" tab to see the corresponding [[Wikipedia:Talk page|talk page]], which contains comments about the page from other Wikipedia users. Click on the "'''+'''" tab to add a new section, or edit the page in the same way as an article page.
  
Consult the [http://meta.wikimedia.org/wiki/Help:Contents User's Guide] for information on using the wiki software.
+
You should also remember to [[Wikipedia:Sign your posts on talk pages|sign your messages]] on [[Wikipedia:Talk pages|talk pages]] and some special-purpose [[Wikipedia:Project namespace|project pages]], but you should '''not''' sign edits you make to regular articles. In [[Wikipedia:Page history|page histories]], the [[MediaWiki]] software keeps track of which user makes each change.

==Minor edits==

{{further|[[Help:Minor edit|Minor edits]]}}
 +
A check to the "minor edit" box signifies that only superficial differences exist between the version with your edit and the previous version: typo corrections, formatting and presentational changes, rearranging of text without modifying content, etc. A ''minor edit'' is a version that the editor believes requires no review and could never be the subject of a dispute. The "minor edit" option is one of several [[Wikipedia:Why create an account%3F#New_editing_options]]
  
* [http://www.mediawiki.org/wiki/Help:Configuration_settings Configuration settings list]
+
==Major edits==
* [http://www.mediawiki.org/wiki/Help:FAQ MediaWiki FAQ]
+
All editors are encouraged to [[Wikipedia:Be_bold|be bold]], but there are several things that a user can do to ensure that major edits are performed smoothly. Before engaging in a major edit, a user should consider discussing proposed changes on the article discussion/talk page. During the edit, if doing so over an extended period of time, the {{[[Template:inuse|inuse]]}} tag can reduce the likelihood of an edit conflict. Once the edit has been completed, the inclusion of an [[Help:Edit summary|edit summary]] will assist in documenting the changes. These steps will all help to ensure that major edits are well received by the Wikipedia community.
* [http://mail.wikimedia.org/mailman/listinfo/mediawiki-announce MediaWiki release mailing list]
+
 
 +
A major edit should be reviewed to confirm that it is consensual to all concerned editors. Therefore, any change that affects the ''meaning'' of an article is major (not minor), even if the edit is a single word.
 +
 
 +
There are no necessary terms to which you have to agree when doing major edits, but the recommendations above have become best practice. If you do it your own way, the likelihood of your edits being re-edited may be higher.
 +
 
 +
==Wiki markup==
 +
{{shortcut|WP:MARKUP}}
 +
 
 +
The '''wiki markup''' is the syntax system you can use to format a Wikipedia page; please see [[Help:Editing]] for details on it, and [[Help:Wikitext examples]] for a longer list of the possibilities of Wikitext.

* A link to another Wiki 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]] en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also [[Wikipedia:Canonicalization]].

Three ways to link to external (non-wiki) sources:
 +
# Bare URL: http://www.wikipedia.com/ (bad style)
 +
# Unnamed link: [http://www.wikipedia.com/] (only used within article body for footnotes)
 +
# Named link: [http://www.wikipedia.com Wikipedia]
 +
 
 +
: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 . _ \ / ~ % - + & # ? ! = ( ) @'''
 +
* 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'''.
 +
* If the "named" version contains a closing square bracket "]", then you must use the [[HTML]] special character syntax, i.e. '''&amp;#93;''' otherwise the [[MediaWiki]] software will prematurely interpret this as the end of the external link.
 +
* 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>

===Invisible text (comments)===
 +
{{main|Wikipedia:Manual of Style#Invisible comments}}
 +
It's uncommon, but on occasion acceptable, to add a hidden comment within the text of an article.  <!--- This is an example of text that won't normally be visible except in "edit" mode. ---> The format is this:
 +
<nowiki><!--- This is an example of text that won't normally be visible except in "edit" mode. ---></nowiki>
 +
 
 +
=== 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 table of contents (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 [[Help:Table]])
 +
*with the usual HTML elements: &lt;table&gt;, &lt;tr&gt;, &lt;td&gt; or &lt;th&gt;.
 +
 
 +
For the latter, and a discussion on when tables are appropriate, see [[Wikipedia:When to use tables]].

'''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 case. For 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 [[help:template|templates]]. This means standardized text chunks (such as [[Wikipedia:Template messages|boilerplate]] text) can be inserted into articles. For example, typing {{tl|stub}} 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: {{tl|disambig}} for disambiguation pages and {{tl|sectstub}} like an article stub but for a section. There are many subject-specific stubs for example: {{tl|Geo-stub}}, {{tl|Hist-stub}}, and {{tl|Linux-stub}}. For a complete list of stubs see [[Wikipedia:WikiProject Stub sorting/Stub types]].

Template:StyleTemplate:Shortcut

See also Wikipedia:Introduction, Wikipedia:Manual of Style, Wikipedia:Tutorial, Help:Editing, and Help:Starting a new page

Wikipedia is a wiki and this means anyone can easily edit any unprotected page and save those changes immediately to that page. After your first edit, you will be a Wikipedia editor!

Introduction

Note: You can use the sandbox to experiment with page editing.

Editing most Wikipedia pages is not difficult. Simply click on the "edit this page" tab at the top of a Wikipedia page (or on a section-edit link). This will bring you to a new page with a text box containing the editable text of the original page. 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 see the difference between the page with your edits and the previous version of the page by pressing the "Show changes" button. If you're satisfied with what you see, be bold and press the "Save page" button. Your changes will immediately be visible to all Wikipedia users.

You can also click on the "Discussion" tab to see the corresponding talk page, which contains comments about the page from other Wikipedia users. Click on the "+" tab to add a new section, or edit the page in the same way as an article page.

You should also remember to sign your messages on talk pages and some special-purpose project pages, but you should not sign edits you make to regular articles. In page histories, the MediaWiki software keeps track of which user makes each change.

Minor edits

Template:Further A check to the "minor edit" box signifies that only superficial differences exist between the version with your edit and the previous version: typo corrections, formatting and presentational changes, rearranging of text without modifying content, etc. A minor edit is a version that the editor believes requires no review and could never be the subject of a dispute. The "minor edit" option is one of several Wikipedia:Why create an account?#New_editing_options

Major edits

All editors are encouraged to be bold, but there are several things that a user can do to ensure that major edits are performed smoothly. Before engaging in a major edit, a user should consider discussing proposed changes on the article discussion/talk page. During the edit, if doing so over an extended period of time, the {{inuse}} tag can reduce the likelihood of an edit conflict. Once the edit has been completed, the inclusion of an edit summary will assist in documenting the changes. These steps will all help to ensure that major edits are well received by the Wikipedia community.

A major edit should be reviewed to confirm that it is consensual to all concerned editors. Therefore, any change that affects the meaning of an article is major (not minor), even if the edit is a single word.

There are no necessary terms to which you have to agree when doing major edits, but the recommendations above have become best practice. If you do it your own way, the likelihood of your edits being re-edited may be higher.

Wiki markup

Template:Shortcut

The wiki markup is the syntax system you can use to format a Wikipedia page; please see Help:Editing for details on it, and Help:Wikitext examples for a longer list of the possibilities of Wikitext.

Links and URLs

What it looks like What you type

London has public transport.

  • A link to another Wiki 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 en.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.
  • The target ("piped") text must be placed first, then the text that will be displayed second.
San Francisco also has
[[public transport|
public transportation]].

San Francisco also has public transportation.

Examples include buses, taxicabs, and streetcars.

  • Endings are blended into the link.
  • Preferred style is to use this instead of a piped link, if possible.
  • Blending can be suppressed by using <nowiki></nowiki> tags, which may be desirable in some instances. Example: a microsecond.
San Francisco also has
[[public transport]]ation.

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

a [[micro]]<nowiki>second
</nowiki>

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).
  • See Wikipedia:Pipe trick for details.

National sarcasm society is a page that does not exist yet.

  • You can create it by clicking on the 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.
[[National sarcasm society]]
is a page 
that does not exist yet.

Wikipedia:How to edit a page is a link to 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]]

The character tilde (~) is used when adding a comment to a Talk page. You should sign your comment by appending four tildes (~~~~) to the comment so as to add your user name plus date/time:

Patricia Zhang 13:40, Jan 14, 2007 (UTC)

Adding three tildes (~~~) will add just your user name:

Patricia Zhang

and adding five tildes (~~~~~) gives the date/time alone:

13:40, Jan 14, 2007 (UTC)
  • The first two both provide a link to your user page.
The character '''tilde''' (~) is used when adding a comment to a Talk page.

  • 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").
  • It is possible to redirect to a section. For example, a redirect to United States History will redirect to the United States page, to the History section if it exists.
#REDIRECT [[United States]]

#REDIRECT [[United States#History|United 
States History]] will redirect to the 
[[United States]] page, to the History 
section if it exists 
  • Link to a page on the same subject in another language by placing a link of the form: [[language code:Title]] in the wiki text of the article.

For example in the article on Plankton, which is available on a lot of other wikis, the interlanguage links would look like so:

[[de:Plankton]] [[es:Plancton]] [[ru:Планктон]] [[simple:Plankton]]
  • While it does not matter where you put these links while editing, it is recommended that these links be placed at the very end of the edit box.
  • These will not be visible in the main text of the article on which they are placed but appear as links in the extreme left margin column of Wikipedia page as part of a separate box under the 'toolbox' titled 'in other languages'. You can check out the links to the corresponding page in wikipedias of other languages for this Wikipedia MOS help page itself.
  • Please see Wikipedia:Interlanguage links and the list of languages and codes.

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

'''What links here''' and
'''Related changes'''
pages can be linked as:

A user's Contributions page can be linked as: Special:Contributions/UserName or Special:Contributions/192.0.2.0

A user's '''Contributions''' page
can be linked as:
[[Special:Contributions/UserName]]
or
[[Special:Contributions/192.0.2.0]]
  • 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.
[[Category:Character sets]]
  • To link to a Wikipedia:Category page without putting the article into the category, use an initial colon (:) in the link.

  • Link to books using their ISBN. This is preferred to linking to a specific online bookstore, because it gives the reader a choice of vendors. However, if one bookstore or online service provides additional free information, such as table of contents or excerpts from the text, then a link to that source will aid the user and is recommended.
  • ISBN links do not need any extra markup, provided you use one of the indicated formats.

  • To include links to images shown as links instead of drawn on the page, use a "media" link.
Using the div tag to separate images from text (note that this may allow images to cover text):
Example:
<div style="display:inline;
width:220px; float:right;">
Place images here </div>
Using wiki markup to make a table in which to place a vertical column of images (this helps edit links match headers, especially in Firefox browsers):
Example: {| align=right
|-
| 
Place images here
|}

See the Wikipedia's image use policy as a guideline used on Wikipedia.

For further help on images, including some more versatile abilities, see the topic on Extended image syntax.

Character formatting

What it looks like What you type

Italicized text
Bold text
Italicized & Bold text

''Italicized text''
'''Bold text'''
'''''Italicized & Bold text'''''

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>
Create codeblocks
#include <iostream.h>
int main ()
{
cout << "Hello World!";
return 0;
}
that are printed as entered
Use <code><pre> Block of Code </pre></code> around the 
block of code.

* The <pre> tags within the codeblock will create formatting 
issues - to solve, display the tags literally with 
&lt;pre&gt;  and  &lt;/pre&gt;

You can use small text for captions.

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

Better stay away from big text, unless it's within small text.

Better stay away from <big>big text</big>, unless
<small> it's <big>within</big> small</small> text.

You can strike out deleted material and underline new material.

You can also mark deleted material and inserted material using logical markup. For backwards compatibility better combine this potentially ignored new logical with the old physical 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.
For backwards compatibility better combine this
potentially ignored new <del>logical</del> with
the old <s><del>physical</del></s> markup.

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.

  • 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.

Ordinary text should use wiki markup for emphasis, and should not use <i> or <b>. However, mathematical formulae often use italics, and sometimes use bold, for reasons unrelated to emphasis. Complex formulae should use <math> markup, and simple formulae 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

Spacing in simple math formulae:
Obviously, x² ≥ 0 is true when x is a real number.

  • 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 when ''x'' is a real number.

Complicated formulae:

<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>

(see also: Chess symbols in Unicode)

No or limited formatting—showing exactly what is being typed

A few different kinds of formatting will tell the Wiki to display things as you typed them—what you see, is what you get!

What it looks like What you type
<nowiki> tags

The nowiki tag ignores [[Wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: →

<nowiki>
The nowiki tag ignores [[Wiki]] ''markup''.
It reformats text by removing newlines 
and multiple spaces.
It still interprets special
characters: &rarr;
</nowiki>
<pre> tags
The pre tag ignores [[Wiki]] ''markup''.
It also doesn't     reformat text.
It still interprets special characters: →
<pre>

Leading spaces

Leading spaces are another way to preserve formatting.

Putting a space at the beginning of each line
stops the text   from being reformatted.

to preserve formatting.

 Putting a space at the beginning of each line
 stops the text   from being reformatted. 
 It still interprets [[Wiki]] ''markup'' and
 special characters: &rarr;

Invisible text (comments)

Template:Main It's uncommon, but on occasion acceptable, to add a hidden comment within the text of an article. The format is this:

<!--- This is an example of text that won't normally be visible except in "edit" mode. --->

Table of contents

At the current status of the wiki markup language, having at least four headers on a page triggers the table of contents (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 Help:Table)
  • with the usual HTML elements: <table>, <tr>, <td> or <th>.

For the latter, and a discussion on when tables are appropriate, see Wikipedia:When to use tables.

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 Template:Tl 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: Template:Tl for disambiguation pages and Template:Tl like an article stub but for a section. There are many subject-specific stubs for example: Template:Tl, Template:Tl, and Template:Tl. For a complete list of stubs see Wikipedia:WikiProject Stub sorting/Stub types.
