 * Wikianvändare kan söka bland tillägg.
 * System administrators can install (or remove) extensions on the MediaWiki installations that they manage.
 * Developers can write new extensions or improve or maintain extensions.

While some extensions are maintained by MediaWiki developers, others were written by third-party developers. As a result, many have bugs, and they are not all guaranteed to be compatible with each other. Some are unmaintained; not all extensions work on all versions of MediaWiki. Use any extension, especially those tagged as insecure, at your own risk. If you are using an extension that requires patches to the core software, be sure to backup your database. This helps avoid the risk of breaking your wiki.

Browsing extensions

Only someone with administration access to the filesystem (and often the database too) on a server can install extensions for MediaWiki, but anyone can check which extensions are active on an instance of MediaWiki by accessing the Special:Version page.

 * 1)  Install your extension. .
 * At the end of the  file, add:
 * This line forces the PHP interpreter to read the extension file, and thereby make it accessible to MediaWiki.
 * Some extensions can conflict with maintenance scripts, for example if they directly access $_SERVER (not recommended).
 * In this case they can be wrapped in the conditional so maintenance scripts can still run.

Upgrading an extension
Some extensions require to be updated whenever you update MediaWiki, while others work with multiple versions. To upgrade to a new version of an extension:

Do not remove the extension configuration present in LocalSettings.php Most extensions will mention if this script needs to be run or not. (Perform backup of your data before executing the script). If you don't have command line access, you can also use the web updater.

 * 1) Replace all the extension files in the  directory with the new files.
 * 1) If the extension requires changes to the MediaWiki database, you will need to run the Update.php maintenance script.
