After your first edit, you are a Wikipedia editor! To request a change to a protected page, you may use any Editprotected template. ===Introduction=== Editing most Wikipedia pages is not very difficult at all. 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. If you just want to experiment, please do so in the sandbox, 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 the Show preview button to see how your changes will look. You can also 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 other 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 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== See Minor edits == 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, 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. ==Wiki markup== The 'wiki markup' is the syntax system you can use to format a Wikipedia page; please see Editing for details on it, and Wikitext examples for a longer list of the possibilities of Wikitext. ===Links and URLs=== {| border=“1” cellpadding=“2” cellspacing=“0”

! 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 en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name “Public transport”. See also Canonicalization.

<pre>\ London has [[public transport]].\ </pre>

San Francisco also has \ public transportation. * Same target, different name. * The “piped” text must be placed 'first', then the text that will be displayed second.

<pre>\ San Francisco also has\ [[public transport|\ public transportation]].\ </pre>

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.

<pre>\ San Francisco also has\ [[public transport]]ation.\ \ Examples include [[bus]]es,\ [[taxicab]]s, and [[streetcar]]s.\ \ a [[micro]]<nowiki>second </nowiki></pre>

See the Manual of Style. * A link to another namespace.

Italics is a link to a section within another page. Links and URLs is a link to another section on the current page. example is a link to an anchor that was created using <div id=“example”>an id attribute</div> * The part after the number sign (#) must match a section heading on the page. Matches must be exact in terms of spelling, case, and punctuation. Links to non-existent sections are not broken; they are treated as links to the top of the page. * Identifiers may be created by attaching an

id="...">

attribute to almost any HTML element. This doesn't work with legacy browsers. * Include “| Link title” to create a stylish link-title.

<pre>\ [[Wikipedia:Manual of Style#Italics]] \ is a link to a section within another\ page.\ \ [[#Links and URLs]] is a link\ to another section on the \ current page.\ \ [[#example]] is a link to an\ anchor that was created \ using\ <div id="example">an id \ attribute\ </div>\ </pre>

Automatically hide stuff in parentheses: kingdom. Automatically hide namespace: Village Pump. Or both: Manual of Style But not: 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).

<pre>\ 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|]]\ </pre> See 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: *# Create a link to it on some other (related) page. *# Save that page. *# 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.

<pre>\ [[National sarcasm society]]\ is a page \ that does not exist yet.\ </pre>

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.

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.

* 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, “#REDIRECT [[United States#History]]” will redirect to the United States page, to the “History” section if it exists.

<pre>\ #REDIRECT [[United States]]\ </pre>

* 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 Interlanguage links and the list of languages and codes.

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 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: '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 hex code of the character, which can be found in the table of 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. '&#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 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: <span\ class="plainlinksneverexpand">\ [http://www.sysinternals.com/\ ntw2k/freeware/winobj.shtml WinObj] Display: [http://www.sysinternals.com/ntw2k/freeware/winobj.shtml WinObj] * See External links for style issues.

Linking to other wikis: # Interwiki link: Hello # Interwiki link without prefix: Hello # Named interwiki link: Wiktionary definition of 'Hello' * All of these forms lead to the URL http://en.wiktionary.org/wiki/Hello * Note that interwiki links use the internal link style. * See Interwiki_map for the list of shortcuts; if the site you want to link to is not on the list, use an external link (see above). * See also How to link to Wikimedia projects. Linking to another language's wiktionary: # bonjour # bonjour # fr:bonjour * All of these forms lead to the URL http://fr.wiktionary.org/wiki/bonjour

ISBN 012345678X ISBN 0-12-345678-X * 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.

Date formats: # July 20, 1969 # 20 July 1969 # 1969-07-20 # 1969-07-20 * Link dates in one of the above formats, so that everyone can set their own display order. If logged in, you can use Preferences to change your own date display setting. * All of the above dates will appear as “20 July 1969” if you set your date display preference to “15 January 2001”, but as “July 20, 1969” if you set it to “January 15, 2001”, or as “1969-07-20” if you set it to “2001-01-15”.

<pre> The pre tag ignores Wiki markup. It also doesn't reformat text. It still interprets special characters: → </pre>

Leading spaces are another way 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: →

=== 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 Table) *with the usual HTML elements: <table>, <tr>, <td> or <th>. For the latter, and a discussion on when tables are appropriate, see When to use tables. ===Variables=== (See also Variable) {|
