Global movement whose mission is to bring free educational content to the world

We believe that knowledge should be free for every human being. We prioritize efforts that empower disadvantaged and underrepresented communities, and that help overcome barriers to participation. We believe in mass collaboration, diversity and consensus building to achieve our goals. Wikipedia has become the fifth most-visited site in the world, used by more than 400 million people every month in more than 270 languages. We have other content projects including Wikimedia Commons, Wikidata and the most recent one, Wikivoyage. We also maintain the MediaWiki engine and a wide collection of open source software projects around it. But there is much more we can do: stabilize infrastructure, increase participation, improve quality, increase reach, encourage innovation. You can help to these goals in many ways.
