New content for "About MediaWiki" description
MediaWiki is an open source wiki engine written in PHP, used by other Wikipedia, Wikimedia projects, and thousands of wikis. You can contribute to MediaWiki in all sorts of ways, including coding, bug testing, translating, and more. A good venue for new contributors are MediaWiki extensions. Most are written in PHP, but many are based in JavaScript, or use HTML, CSS, and more. Gadgets, which are short bits of CSS or JavaScript, are available as well. You can also work on templates made with Lua, improve skins, and help out with mobile development. Ready? Check out our Starter Kit!
