Customization

MediaWiki can be customized in several ways. It is distributed as GPL. You may thus contribute your own skins, extensions and patches.

Configuration

 * Configuration parameters may be easily defined in a LocalSettings.php file.
 * Interface messages can be modified in the wiki.
 * Extensions and patches are provided by the community, some of which are available here. They generally fall into one of these categories:
 * Extensions defining a new wiki tag (see also: Write your own MediaWiki extension)
 * Extensions defining a new special page (see also: Writing a new special page)
 * MediaWiki is (somewhat) multilingual.
 * The FAQ contains a lot of useful customisation info.

Skins
Look and feel can be modified by using different skins. There is a gallery of user styles which gives examples of the kind of skin customization that is possible.
