+## Development
+
+All `git commit` mesage must follow below syntax:
+
+```bash
+type(scope?): subject  #scope is optional
+```
+
+support type：
+
+```bash
+- **feat**: add new feature
+- **fix**: fix bug or patch feature
+- **ci**: CI
+- **chore**: modify config, nothing to do with production code
+- **docs**: create or modifiy documents
+- **refactor**: refactor project
+- **revert**: revert
+- **test**: test
+```
+
+Most of time, we just use `feat` and `fix`.
