Cite your sources
Wikipedia articles should focus on describing facts in a neutral fashion. When writing about facts, cite sources that verify the information being presented. Stick to a factual style even when writing about fiction or opinions. Providing references is particularly important for controversial opinions—instead of using weasel words like "some people believe…," you should cite sources to help readers know who believes what, and why.
