+## Releasing the SDK
+
+To release a new version of the SDK, follow these steps:
+
+1. Update the version in `src/a2ui/version.py`.
+2. Run the release script from the `agent_sdks/python` directory:
+
+   ```bash
+   ./release.sh
+   ```
+
+The script will build the package, upload it to the Artifact Registry, and trigger the release pipeline.
+
+## Tracking the release
+
+1. Check the release status through Sponge: go/spng2?q=PROJECT%3Aa2ui%2Fpypi
+2. You will see logs for the jobs involved in your release. A successful release is confirmed when the final job, named "publisher", completes successfully.
