+=head1 NAME
+
+GiteaRefs - Hydra plugin for retrieving the list of references (branches or
+tags) from Gitea following a certain naming scheme
+
+=head1 DESCRIPTION
+
+This plugin reads the list of branches or tags using Gitea's REST API. The name
+of the reference must follow a particular prefix. This list is stored in the
+nix-store and used as an input to declarative jobsets.
+
+=head1 CONFIGURATION
+
+The plugin doesn't require any dedicated configuration block, but it has to
+consult C<gitea_authorization> entry for obtaining the API token. In addition,
+
+The declarative project C<spec.json> file must contains an input such as
+
+   "pulls": {
+     "type": "gitea_refs",
+     "value": "[gitea_hostname] [owner] [repo] heads|tags [scheme] - [prefix]",
+     "emailresponsible": false
+   }
+
+In the above snippet, C<[gitea_hostname]> must be set to the hostname of the
+repository's Gitea instance.
+
+C<[owner]> is the repository owner and C<[repo]> is the repository name. Also
+note a literal C<->, which is placed there for the future use.
+
+C<heads|tags> denotes that one of these two is allowed, that is, the third
+position should hold either the C<heads> or the C<tags> keyword. In case of the former, the plugin
+will fetch all branches, while in case of the latter, it will fetch the tags.
+
+C<scheme> should be set to either https or http, depending on what the Gitea
+host supports.
+
+C<prefix> denotes the prefix the reference name must start with, in order to be
+included.
+
+For example, C<"value": "projects.blender.org blender blender heads https - blender-v/"> refers to
+L<https://projects.blender.org/blender/blender> repository, and will fetch all branches that
+begin with C<blender-v/>.
+
+=head1 USE
+
+The result is stored in the nix-store as a JSON I<map>, where the key is the
+name of the reference, while the value is the complete Gitea response. Thus,
+any of the values listed in
+L<https://docs.gitea.com/api#tag/repository/operation/repoListAllGitRefs> can be
+used to build the git input value in C<jobsets.nix>.
