Help:Extensions

Extensions are features and add-ons developed for MediaWiki, the software platform that Wikia runs on. They are designed by third-party developers (that is to say, not Wikia or MediaWiki staff) for the purpose of either expanding the function of a wiki or overriding a built-in MediaWiki feature for customization purposes.

See w:Category:Extensions for help pages on Wikia Help. Note this article may not be completely up to date.
