= Footnotes Category Keys
:description: Reference list of the available footnotes category keys and their value types.
:navtitle: Footnotes
:source-language: yaml

The keys in the `footnotes` category control the style of the footnotes list at the end of a chapter (`book` doctype) or document (other doctypes).
The styling of the links is controlled by the xref:link.adoc[global link styles].
If the `footnotes-title` attribute is set in the document, its value will be used as the caption of the footnotes list.
As such, it will be styled as a xref:caption.adoc[block caption] and can also be configured independently of other captions.
