This guideline is about self-references and specifies which types of self-references should be avoided and which kinds are acceptable. A self-reference in an article usually mentions Wikipedia directly or tells readers to take an action on Wikipedia, such as editing the article.Typically, self-references within Wikipedia articles to the Wikipedia project should be avoided. Others, such as maintenance templates, may be necessary.This Wikipedia article discusses… — While Wikipedia is not a dictionary… (in an article about a certain term) — Edit this page…Click here to see moreFree content projects, such as this website … (Writing about Wikipedia itself)This article was criticised by…Self-references are sometimes found in the templates and the categories. Some of these are necessary or intrinsic to the purpose of the page, as with disambiguation information at the top of category pages and in {{stub}} templates, which encourage readers to edit the page. Unnecessary self-references are not encouraged in templates or categories, due to the need of third-party users to either delete those templates or modify them to remove the Wikipedia references. For example, all {{navbox}} templates should provide a list of related articles, but none of them should label these pages as "Wikipedia articles" or as "Related articles on this website".When forced to use templates like this, you should use them in a way such that the article still makes sense when the template is removed, in order to facilitate automated removal.Wikipedia project coordination pages should be under Category:Wikipedia administration, not in categories that contain main-namespace articles by topic. (A small number of articles about Wikipedia are in the mainstream categories and this is OK.) User pages may be categorized under Category:Wikipedians, but not in any of the subcategories under Category:People.The self-reference template, {{Selfref}}, is used to mark pieces of text and links that wouldn't make sense on copies of Wikipedia. This gives the ability to programmatically remove all such references or transform them into external links. Thus, the end product can have all of its self-references removed automatically for users, such as forks and mirrors. This template is most often used as a hatnote template to help guide editors from an article to a related Wikipedia policy or guideline page in the Wikipedia project namespace.In cases where a Wikipedia page should link to Wikipedia itself (for instance, at Wikipedia) and this link should be kept on mirrors, the format {{srlink|link}} can be used to write the link as external, rather than internal when outside of Wikipedia, to prevent it breaking in mirrors. For instance: Wikipedia's Main Page (made by {{srlink|Main Page|Wikipedia's Main Page}}) as opposed to Wikipedia's Main Page ([[Main Page|Wikipedia's Main Page]]).
