+## Commit Rules
+- Use Conventional Commits format for all commit messages
+- Format: `<type>(<scope>): <description>`
+- Types:
+  - `feat`: A new feature
+  - `fix`: A bug fix
+  - `docs`: Documentation changes
+  - `style`: Changes that do not affect code meaning (formatting, etc.)
+  - `refactor`: Code changes that neither fix a bug nor add a feature
+  - `perf`: Performance improvements
+  - `test`: Adding or modifying tests
+  - `chore`: Changes to build process or auxiliary tools
+- Scope is optional and should be the module or component affected
+- Description should be concise, in the imperative mood, and not capitalized
+- Use body for more detailed explanations if needed
+- Reference issues in the footer with `Fixes #123` or `Relates to #123`
+- Examples:
+  - `feat(auth): add password reset functionality`
+  - `fix(api): correct validation error in client registration`
+  - `docs: update API documentation for new endpoints`
+  - `refactor(services): improve error handling in authentication`
+
