Using {{Hatnote}} formats text into the standard stylistic for a wiki hatnote. That produces a short note placed at the top of an article to provide disambiguation of closely related terms or summarise a topic, explaining its boundaries.
Function[]
This template is primarily used to add a correctly formatted hatnote to a page. Often, but not always, this is a disambiguation link at the top of article pages. It places an HTML div- / div block around the text entered as its only argument, which provides standardized formatting (contents are indented and italicized in most displays); it also isolates the contained code to make sure that it is interpreted correctly.
This template is also used as the "meta-template" for additional specialized disambiguation link templates.
The template does not automatically create links of any kind. Links and other desired formatting must be explicitly added, using normal wiki markup.
