About Mediawiki
This GitHub repository is a mirror of MediaWiki, a free and open-source wiki software package written in PHP. The README states that it runs Wikipedia and other Wikimedia projects, which serve hundreds of millions of people each month. The software is licensed under the GNU General Public License, version 2 or later, according to the repository's COPYING file.
MediaWiki is described as feature-rich and extensible, with hundreds of extensions, and as suitable for both small and large sites. The project states that it is localised in over 350 languages. The repository is a mirror from gerrit.wikimedia.org, and the README directs contributors to the developer access page on mediawiki.org rather than to this repository.
