+## Sync labels on another repository
+
+It is also possible to specify a repository as an input to the action. This is useful if you want to store your labels somewhere centrally and modify multiple repository labels.
+
+**Note: The default `GITHUB_TOKEN` will not have permissions to operate on other repositories so you must specify a personal access token in your secrets.**
