   Some examples:
 
   * `github:edolstra/dwarffs`
   * `github:edolstra/dwarffs/unstable`
   * `github:edolstra/dwarffs/d3f2baba8f425779026c6ec04021b2e927f61e31`

+  GitLab repositories. The following attributes are required:
+
+  * `owner`: The owner of the repository.
+
+  * `repo`: The name of the repository.
+
+  Like `github`, these are downloaded as tarball archives.
+
+  The URL syntax for `gitlab` flakes is:
+
+  `gitlab:<owner>/<repo>(/<rev-or-ref>)?(\?<params>)?`
+
+  `<rev-or-ref>` works the same as `github`. Either a branch or tag name
+  (`ref`), or a commit hash (`rev`) can be specified.
+
+  Since GitLab allows for self-hosting, you can specify `host` as
+  a parameter, to point to any instances other than `gitlab.com`.
