English: This is a documentary about Wikimania 2013 in Hong Kong. Wikipedia is the most comprehensive encyclopedia that has ever existed. Remarkably, its content is edited and maintained entirely by volunteers from around the world. Hosted by a non-profit that is funded by donations, Wikipedia is shared with around 500,000,000 people every month. The international conference for users of Wikipedia - called Wikimania - has been organized in a different city every year since 2005 to present and discuss topics related to free knowledge, free culture, and open-source software. Wikipedia is part of a social movement that values transparency, collaboration, and the free and open sharing of knowledge.
