ref and relref look up a content page by logical name (ref) or relative path (relref) to return the permalink:

{{ ref . "about.md" }}

{{% note "Usage Note" %}} ref looks up Hugo "Regular Pages" only. It can't be used for the homepage, section pages, etc. {{% /note %}}

These functions are used in two of Hugo's built-in shortcodes. You can see basic usage examples of both ref and relref in the shortcode documentation.

For an extensive explanation of how to leverage ref and relref for content management, see Cross References.
