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. Though you may use MediaWiki every day on Wikipedia, you might not be aware of its use in other Wikimedia projects, including Wikibooks, Wikivoyage, and more. There is much work to be done in order to increase worldwide participation and stabilize the wiki infrastructure. Helping out may be daunting at first, but tutorials and IRC channels are available to help. You can help out MediaWiki in all sorts of ways, including coding, bug testing, translating, and more.
