+## How to create a new release
+
+- Update the version info in [`build.gradle`](build.gradle)
+- Create a PR to master branch
+- Once the PR is merged, create a release tag (e.g., `release-2.5.2_1.19.0`, see [`release.yaml`](.github/workflows/release.yaml)) 
+and push the tag to the master branch to trigger the release creation. Note that here we disabled the workflow
+[`publish.yaml`](.github/workflows/publish.yaml). Otherwise, the action `gradlew publish` in both workflows conflict
+with each other.
