MediaWiki

MediaWiki is a popular and free, open-source wiki software package written in PHP. It serves as the platform for Wikipedia and its sister projects, which deliver content in over 280 languages to more than half a billion people each month. MediaWiki's reliability and robust feature set have earned it a large and vibrant community of third-party users and developers.

MediaWiki is:

• feature-rich and extensible, both on-wiki and with over 2,000 extensions;
• scalable and suitable for both small and large sites;
• available in your language; and
• simple to install, working on most hardware/software combinations.

For system requirements, installation, and upgrade details, see the files RELEASE-NOTES, INSTALL, and UPGRADE.
