 - `npm test` - Run the test suite
 - `npm run format` - Format code with Prettier
 - `npm run inspector` - Run the MCP Inspector against the server
+- `npm run semantic-release` - Run semantic release (automated in CI)
 
 ### Running Tests
 
 ```bash
 npm test
 ```
 
+### 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/).
+
+#### Required Secrets
+
+For the automated release workflow to function, the following secrets must be configured in the GitHub repository:
+
+- `GITHUB_TOKEN` - Automatically provided by GitHub Actions for creating releases and updating the repository
+- `NPM_TOKEN` - Required for publishing packages to npm. Generate this token from your npm account with publish permissions
+
+#### Commit Message Format
+
+**⚠️ Important:** This project uses automated semantic versioning. The commit message format directly determines version bumps and changelog generation.
+
+The project follows the [Conventional Commits](https://www.conventionalcommits.org/) specification. Each commit message must be structured as:
+
+```
+<type>[optional scope]: <description>
+
+[optional body]
+
+[optional footer(s)]
+```
+
+**Supported commit types:**
+- `feat:` - new features (triggers **minor** version bump: 1.0.0 → 1.1.0)
+- `fix:` - bug fixes (triggers **patch** version bump: 1.0.0 → 1.0.1)  
+- `feat!:` or `fix!:` - breaking changes (triggers **major** version bump: 1.0.0 → 2.0.0)
+- `docs:`, `style:`, `refactor:`, `test:`, `chore:` - maintenance (no version bump)
+
+**Examples:**
+```
+feat: add new search functionality
+fix: resolve timeout issue in API calls
+feat!: remove deprecated getBook method
+docs: update API documentation
+```
+
+**Why this matters:**
+- ✅ Proper format → Automatic version bump and release
+- ❌ Wrong format → No release, manual intervention required
+- 📝 Commit messages become the public changelog
+
+The project validates commit messages automatically to ensure releases work correctly.
+
+#### Development Workflow
+
+The project includes automatic validation to ensure proper commit message format:
+
+- **Pre-commit hooks** validate code quality with linting and tests
+- **Commit message validation** ensures conventional commit format using [commitlint](https://commitlint.js.org/)
+- **Invalid commit messages** are rejected before they reach the repository
+
+To manually validate a commit message:
+```bash
+npm run commitlint
+```
