In Wikipedia, notability is a word that is used to explain what makes things important enough to be the subject of a Wikipedia article. The topic of an article should be notable, or "worthy of notice". Notability is different from "fame", "importance", or "popularity", although these may affect it. A topic is thought to be notable enough to be the subject of an article if it meets the general guidelines below. If an article currently does not cite reliable secondary sources, that does not necessarily mean that its topic is not notable.
These notability guidelines are only about the encyclopedic suitability of topics for articles. They do not directly limit the content of articles. Relevant content policies include: Neutral point of view, Verifiability, No original research, What Wikipedia is not, and Biographies of living persons.
