MediaWiki is a popular «Wiki»-system, written in PHP and originally created as the Wikipedia's engine. MediaWiki is very extensible — there is more than 1700 useful extensions, and it’s very easy to write a new one.

Mediawiki4Intranet is a MediaWiki distribution containing many extensions and patches useful for intranet (and not only for intranet). It is important to mention that all these extensions are improved and tested to work together — integrations bugs are fixed and some features are added.

This page (english documentation) just contains the basic information. For more information see russian documentation.

Installation information: see #Installation.

The primary source code repositories are under Mediawiki4Intranet github organisation. 'configs' repository contains bundle index and configuration files, 'core' is the patched MediaWiki, other repositories are for extensions and skins.

Some of the extensions are taken directly from Wikimedia Git repositories, like for XXX extension:

Mediawiki4Intranet version may be less than the last stable release, because the differences between MediaWiki versions are not that big in terms of new features, but newer releases are less stable and patches always need updating.
