This guideline is a part of the English Wikipedia's Manual of Style.
|This page in a nutshell: Wikipedia's free content is reused in many places: do not assume that the reader is reading Wikipedia, or indeed any website. Articles may refer to themselves, but they shouldn't refer to Wikipedia in a non-neutral fashion except under special circumstances.|

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.
Although self-references within Wikipedia articles to the Wikipedia project should usually be avoided, there are exceptions. Some examples of acceptable self-references are articles about Wikipedia, categories, and maintenance templates.
