 Our Python API CI would automatically run code style checker and unittest when you submit pull request in
 GitHub, you could also run static check locally.
 
+We recommend [pre-commit](https://pre-commit.com/) to do the checker mentioned above before you develop locally. 
+You should install `pre-commit` by running
+
+```shell
+python -m pip install pre-commit

+in your development environment and then run `pre-commit install` to set up the git hooks scripts. After finish
