New content for "About MediaWiki" description
MediaWiki is a free software open source wiki package written in PHP, originally for use on Wikipedia. It is now used by several other projects of the non-profit Wikimedia Foundation and by many other wikis. It uses a markup language designed for easy collaborative editing inside of HTML forms. Many tasks, including coding and documentation work, are available to help improve the MediaWiki software and reach the Wikimedia Foundation's goal of free knowledge for everyone.
