    History

    Wikipedia was founded as an offshoot of Nupedia, a now-abandoned project to produce a free encyclopedia, begun by the online media company Bomis. Nupedia had an elaborate system of peer review and required highly qualified contributors, but articles' writing was slow. During 2000, Jimmy Wales (founder of Nupedia and co-founder of Bomis), and Larry Sanger, whom Wales had employed to work on the encyclopedia project, discussed ways of supplementing Nupedia with a more open, complementary projec...

    Anyone with Web access can edit Wikipedia, and this openness encourages the inclusion of a tremendous amount of content. About 120,000 editors—from expert scholars to casual readers—regularly edit Wikipedia, and these experienced editors often help to create a consistent style throughout the encyclopedia, following our Manual of Style. Several mechanisms are in place to help Wikipedia members carry out the important work of crafting a high-quality resource while maintaining civility. Editors...

    Basic navigation

    Wikipedia articles are all cross-referenced. Highlighted text like this means "click here" for in-depth information. (Hovering is probably deep enough.) There are other links towards the ends of most articles, for other articles of interest, relevant external websites and pages, reference material, navigational templates, and organized categories of knowledge which can be searched and traversed in a loose hierarchy for more information. Some articles may also have links to dictionary definiti...

    Research

    As wikidocuments, articles are never considered complete and may be continually edited and improved. Over time, this generally results in an upward trend of quality and a growing consensus over a neutral representation of information. Users should be aware that not all articles are of encyclopedic quality from the start: they may contain false or debatable information. Indeed, many articles start their lives as displaying a single viewpoint; and, after a long process of discussion, debate, an...

    Anyone can contribute to Wikipedia by clicking on the Edit tab in an article, and editors are encouraged to be bold. To get started, the intro tutorial has helpful advice. Also, creating an account offers many benefits. Editors are expected to add only verifiable and factual information rather than personal views and opinions, and to remain civil when discussing issues. Vandals will have their edits reverted and be blockedfrom editing. Most articles start as stubs, but after many contributions, they can become featured articles. All editors are unpaid volunteers, including administrators, trusted editors who are given elevated permissions. The ease of editing Wikipedia results in many people editing. That makes updating the encyclopedia very quick. Every page has an associated talk pagetab, where improvements to it are discussed.

    Wikipedia uses MediaWiki software, the open-source program used not only on Wikimedia projects but also on many other third-party websites. The hardware supporting the Wikimedia projects is based on several hundred servers in various hosting centers worldwide. Full descriptions of these servers and their roles are available on this Meta-Wiki page. For technical information about Wikipedia, check Technical FAQ. Wikipedia publishes various types of metadata; and, across its pages, are many thousands of microformats.

    Wikipedia is run as a communal effort. It is a community project whose result is an encyclopedia. Feedback about the content should, in the first instance, be raised on the discussion pages of those articles. Be boldand edit the pages to add information or correct mistakes.

    Wikipedia is hosted by the Wikimedia Foundation, a non-profit organization that also hosts a range of other projects: Please note that while other sites may also use MediaWiki software and therefore look like Wikipedia [dot org]—"wiki-" or "-pedia" or anything similar—the only projects which are part of the Wikimedia Foundation are those listed above.
