The following pages will give you guidance on the style and content of Wikipedia articles, and tell you about the Wikipedia community and important policies and conventions. This is a basic tutorial, not an extensive manual or interactive learning environment. For more details on any information in the tutorial, you can click on the links to other resource pages as you read, opening them in a separate browser window or tab.

As a new contributor, you may feel a little overwhelmed by the sheer size and scope of this site. No new user can understand everything at first, and it's acceptable to use common sense as you go about your editing. Wikipedia not only allows you to create, revise, and edit articles, but it wants you to do it (see be bold)! You just need to remember that though there are many protocols, perfection is not required, as Wikipedia is a work in progress. Collaborative editing means that incomplete or poorly written first drafts can evolve over time into excellent articles.
The goal of a Wikipedia article is to create a comprehensive and neutrally written summary of existing mainstream knowledge about a topic. Accordingly, Wikipedia does not publish original research. An encyclopedia is, by its nature, a tertiary source that provides a survey of information already published in the wider world. So we require that information be verifiable in reliable external sources. Ideally, all information should be actually cited to reliable sources. When adding content and creating new articles, an encyclopedic style with a formal tone is important. Instead of essay-like, argumentative, or opinionated writing, Wikipedia articles should have a straightforward, just-the-facts style.
Wikipedia does not have many hard-and-fast rules; but policies, guidelines, and formatting norms are developed by the community to describe best practices, clarify principles, resolve conflicts, and otherwise further our goals. General social norms should be followed by all editors. The Wikipedia community comprises people from many countries and cultures, with different views, perspectives, opinions, and backgrounds—sometimes varying widely. Editors should treat each other respectfully, work together collegially, and avoid behaviour that would be widely seen as unacceptable, disruptive, tendentious, or dishonest.

Wikipedia also has "topic specific tutorials"; and The Wikipedia Adventure a comprehensive and fun 7-mission interactive guided tour, which covers all the essentials about editing and the expectations and norms of the Wikipedia community.
