+          - [ ] Review changelog entries for accuracy
+          - [ ] Verify version in `ndc-lambda-sdk/package.json` is correct
+          - [ ] Ensure all CI checks pass
+
+          ### Post-merge Instructions
+          After merging, create and push the tag to trigger the release workflow:
+
+          ```bash
+          git checkout main
+          git pull origin main
+          git tag ${{ github.event.inputs.version }}
+          git push origin ${{ github.event.inputs.version }}
+          ```
+
+          > **Note:** The release workflow will automatically publish to npm and create the GitHub release.
