Wikimedia envisions a world in which every single human being can freely share in the sum of all knowledge. It spans various projects, local chapters and support structures of the non-profit Wikimedia Foundation.

There are 13 projects that Wikimedia officially supports including Wikipedia, a fifth most popular site on the internet and a well known free knowledge project in the world. Wikipedia is used by more than 400 million people every month in over 300 languages. Some of Wikipedia's sister projects are Wikimedia Commons, Wikidata, MediaWiki, Wikivoyage, etc. All major projects of Wikimedia are collaboratively developed by users around the world using the MediaWiki software.

There is much more to do that you can help Wikimedia achieve: stabilize infrastructure, increase participation, improve quality, increase reach and foster innovation.
