Wikipedia:Five pillars

Wikipedia's rules can be thought of as five pillars that show how the project works:

Wikipedia is an encyclopedia

Wikipedia is an encyclopedia that has elements of general and specialized encyclopedias, almanacs, and gazetteers. All articles must follow our no original research policy, and strive for verifiable accuracy: unreferenced material may be removed, so please provide references. Wikipedia is not the place to insert personal opinions, experiences, or arguments. Wikipedia is not an indiscriminate collection of information. Wikipedia is not a soapbox, an advertising platform, a vanity press, an experiment in anarchy or democracy, or a web directory. It is not a newspaper or a collection of source documents; these kinds of content should be contributed to the Wikimedia sister projects.

Wikipedia has a neutral point of view

Wikipedia has a neutral point of view, which means we strive for articles that advocate no single point of view. Sometimes this requires representing multiple points of view, presenting each point of view accurately, providing context for any given point of view, and presenting no one point of view as "the truth" or "the best view." It means citing verifiable, authoritative sources whenever possible, especially on controversial topics. When a conflict arises regarding neutrality, declare a cool-down period and tag the article as disputed, hammer out details on the talk page, and follow dispute resolution.

Wikipedia is free content

Wikipedia is free content that anyone may change. All text is available under the GNU Free Documentation License (GFDL) and may be distributed or linked accordingly. Recognize that articles can be changed by anyone and no individual controls any specific article; therefore, any writing you contribute can be mercilessly changed and redistributed at will by the community. Do not infringe on copyright or submit work licensed in a way incompatible with the GFDL.

Wikipedia has a code of conduct

Wikipedia has a code of conduct: Respect your fellow Wikipedians even when you may not agree with them. Be civil. Avoid conflicts of interest, personal attacks or sweeping generalizations. Find consensus, avoid edit wars, follow the three-revert rule, and remember that there are 254,205 articles on the Simple English Wikipedia to work on and discuss. Act in good faith, do not make problems to prove something, and assume good faith on the part of others. Be open and welcoming.

Wikipedia has no firm rules

Wikipedia does not have firm rules besides the five general principles presented here. Be bold in changing, moving, and modifying articles. Although it should be aimed for, perfection is not required. Do not worry about making mistakes. All prior versions of articles are kept, so there is no way that you can accidentally damage Wikipedia or irretrievably destroy content. Remember, whatever you write here will be preserved for posterity.
