+## Releasing
+
+### release-it
+
+The project uses `release-it` with the `@release-it/conventional-changelog` plugin for automated releases.
+
+```bash
+npm run release
+```
+
+This will:
+1. Run lint, typecheck, and tests
+2. Bump version based on conventional commits
+3. Generate/update CHANGELOG.md
+4. Create git tag
+5. Push to GitHub
+6. Create GitHub Release with changelog
+7. Publish to npm
+
