+# github-label-sync
+
+> A command-line interface for synchronizing GitHub labels.
+> More information: <https://github.com/Financial-Times/github-label-sync>.
+
+- Synchronize labels using a local `labels.json` file:
+
+`github-label-sync --access-token {{token}} {{repository_name}}`
+
+- Synchronize labels using a specific labels JSON file:
+
+`github-label-sync --access-token {{token}} --labels {{url|path/to/json_file}} {{repository_name}}`
+
+- Perform a dry run instead of actually synchronizing labels:
+
+`github-label-sync --access-token {{token}} --dry-run {{repository_name}}`
+
+- Keep labels that aren't in `labels.json`:
+
+`github-label-sync --access-token {{token}} --allow-added-labels {{repository_name}}`
+
+- Synchronize using the `GITHUB_ACCESS_TOKEN` environment variable:
+
+`github-label-sync {{repository_name}}`
