+#### Changelog Generation with Conventional Changelog
+
+After calling the `prepare_release.sh` script, it is recommended to manually trigger the changelog generation script (which uses [conventional-changelog](https://github.com/conventional-changelog/conventional-changelog)).
+
+1. **Conventional Commit Messages**:
+
+   - Ensure all commit messages follow the conventional commit format, which helps in automatic changelog generation.
+   - Commit messages should be in the format: `type(scope): subject`.
+
+2. **Enforcing Commit Messages**:
+
+   - We enforce conventional commit messages using [Lefthook](https://github.com/evilmartians/lefthook) with [commitlint](https://github.com/conventional-changelog/commitlint).
+   - This setup ensures that all commit messages are validated before they are committed.
+
+3. **Generate Changelog**:
+   - Run the changelog generation script to update the `CHANGELOG.md` file:
+     ```sh
+     npm run changelog
+     ```
+   - Review and commit the updated changelog before proceeding with the release.
+
+#### Merging the Release Branch
+
 - Create PR on develop branch
 - Merge develop in main branch
