Extending MediaWiki

There are 5 main extension points that allow developers to add features and functionality to MediaWiki or to change existing functionality. MediaWiki has been designed to allow for modification without changing the "core code". This makes it easy to update to a new version of MediaWiki without having to manually merge in old extension code changes. The extension points are:

Hooks - Every time "X" happens do something... Tag Extensions - Create a new tag like: <newtag>...</newtag> Parser Functions - Create a new command like: {{#if:...|...|...}} Special Pages - Add a new special page. Skins - Change the look and feel of MediaWiki.
