+### Releases
+
+This project uses [semantic-release](https://semantic-release.gitbook.io/) for automated versioning and publishing. Releases are automatically created when commits are pushed to the `main` branch using [conventional commit messages](https://www.conventionalcommits.org/).
+
+Commit message format:
+- `feat:` - new features (triggers minor version bump)
+- `fix:` - bug fixes (triggers patch version bump)  
+- `feat!:` or `fix!:` - breaking changes (triggers major version bump)
+- `docs:`, `style:`, `refactor:`, `test:`, `chore:` - no version bump
