There are five types of links in MediaWiki:

Internal links to other pages in the wiki
External links to other websites
External links to internal pages in the wiki
Interwiki links to other websites registered to the wiki in advance
Interlanguage links to other websites registered as other language versions of the wiki

Internal links

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. Selflinks to the current page are not transformed in URLs but displayed in bold. (If you really want to link to the current page, use an anchor (see below), or [[#top|current page]] which always links to the top.)

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).

External links

To add an external link, enclose the name of the page you want to link to in single square brackets. When you save the page, you'll see the new link pointing to your page, with an arrow icon after it to show that it was coded with single bracket external link syntax, and thus may lead to another site.

External links to internal pages

To add an external link to a page on the same wiki using parameters, you may need to use external link syntax. Enclose the name of the page you want to link to in single square brackets. When you save the page, you'll see the new link pointing to your page, with an arrow icon after it. This is often useful if you want to link internally on a wiki, but need query parameters in the URL, which may not work with normal internal links in some circumstances.

Description	You type	You get
External link to the current page's edit page	[http://www.mediawiki.org/w/index.php?title=Help:Links&action=edit Edit]	Edit
External link to the current page's edit page using the fullurl parser function	[{{fullurl:{{PAGENAME}}\|action=edit}} Edit] See also Help:Magic_words#URL_data and #External links	Edit
External link to the current page's edit page, and styled to look like an internal link	<span class="plainlinks">[http://www.mediawiki.org/w/index.php?title=Help:Links&action=edit Edit]</span> The plainlinks class can be used in cases where you want an external link to look like an internal one, by suppressing the icon that normally appears after it.

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 links with the internal link markup to a website registered in advance. For example, you can link to the Sunflower article on http://en.wikipedia.org by typing [[wikipedia:Sunflower]], which will result in a link wikipedia:Sunflower. This is because http://en.wikipedia.org/wiki/ is registered to your wiki by default with the prefix of wikipedia. This link may not work properly, if the admin of your wiki has changed the setting. Unlike internal links, interwiki links do not use page existence detection, so an interwiki link will appear blue even if the page does not exist on the remote wiki.

Similar to internal page links, you can create piped links, with alternate link label, e.g. [[wikipedia:Sunflower|big yellow flower]], this is the link big yellow flower.

Basically this is an abbreviation for longer URLs. A very similar link could be created as a normal external link by typing [http://en.wikipedia.org/wiki/Sunflower big yellow flower], but interwiki links allow you to type out an easy and compact link, almost as if you are linking to a page on your own wiki.

More details are at Template:Mediawiki. To edit the Template:Mediawiki on your site, see the Template:Mediawiki.

Interlanguage links

If your wiki has other language versions, you may find “interlanguage links” in the sidebar, just below toolbox in the box named “in other languages.”

Interlanguage links behave similarly to interwiki links, except that they are listed in the sidebar. To create an interlanguage link from a page, just type [[language prefix:pagename]] wherever you like in the page; the language prefix is the prefix specified at your wiki for the other language version (typically the ISO language code).

If you want to make the interlanguage link appear in the content of the page, you can add a colon before the language prefix:

[[:en:Sunflower]] → en:Sunflower

When link is both interwiki and interlanguage, the order is wikipedia:en:Sunflower.
