 **Code Format:**
 
-We adopt [PEP8 rules](https://peps.python.org/pep-0008/) for arranging and formatting Python code. Please use a code formatter tool in your IDE to reformat the code before submitting the PR.
+We adopt [`black`](https://github.com/psf/black) for arranging and formatting Python code. To streamline the contribution process, we set up a [pre-commit hook](https://pre-commit.com/) to format the code under `knowledge_storm/` before committing. To install the pre-commit hook, run:
+```
+pip install pre-commit
+pre-commit install
+```
+The hook will automatically format the code before each commit.

 - [2024/05] We add Bing Search support in [rm.py](knowledge_storm/rm.py). Test STORM with `GPT-4o` - we now configure the article generation part in our demo using `GPT-4o` model.
 - [2024/04] We release refactored version of STORM codebase! We define [interface](knowledge_storm/interface.py) for STORM pipeline and reimplement STORM-wiki (check out [`src/storm_wiki`](knowledge_storm/storm_wiki)) to demonstrate how to instantiate the pipeline. We provide API to support customization of different language models and retrieval/search integration.
