+Please note that the `services.gitea-actions-runner.instances.<name>.labels` key may be set to `[]` (an empty list) to use the packaged Forgejo instance list. One of `virtualisation.docker.enable` or `virtualisation.podman.enable` will need to be set. The default Forgejo image list is populated with docker images.

+    ipv6 = true;
+  };
