This page in a nutshell: Hatnotes provide links at the very top of an article or a section to help readers locate a different article if the one they are viewing is not the one they're looking for.

Hatnotes are short notes placed at the very top of a page or a section, in the way that a hat is placed on top of one's head. For an example, see the notes in italics immediately preceding the boxes above. The purpose of a hatnote is to help readers locate a different article if the one they are at is not the one they're looking for. Readers may have arrived at the article containing the hatnote because:

• They were redirected.
• They may be seeking an article that uses a more specific, disambiguated title.
• They may be seeking an article with a similar name to, or that otherwise might be confused with, the article with the hatnote.

Hatnotes provide links to the possibly sought article or to a disambiguation page.

The six basic rules of hatnotes are:

1. Link directly to other articles; do not pipe non-disambiguation links. With regard to linking to redirects, follow any applicable rules in the disambiguation guideline. For example, links to disambiguation pages should always end in "(disambiguation)".
2. Keep explanations to a minimum; explain vital information only, letting the lead section and body of the article to clarify things for the reader.
3. Mention other topics and articles only if there is a reasonable possibility of a reader arriving at the article either by mistake or with another topic in mind.
4. However, if a notable topic X is commonly referred to as "Foo", but the article "Foo" is not about X, there must be a hatnote linking to the article on X or linking to a disambiguation page that contains a link to the article on X.
5. Ideally, limit hatnotes to just one at the top of the page or section. Multiple hatnotes may be appropriate when they serve different purposes, such as disambiguating topics with similar names and explaining redirects. (In such cases, consider using {{hatnote group}}.)
6. Refrain from having redlinks in your hatnotes. As opposed to having redlinks in the writing of the article, redlinks in hatnotes do not help and add to a large backlog.
