 ## Reporting Bugs/Feature Requests
 
 We welcome you to use the [Bug Reports](../../issues/new?template=bug_report.yml) file to report bugs or [Feature Requests](../../issues/new?template=feature_request.yml) to suggest features.
 
 For a list of known bugs and feature requests:
+
 - Check [Bug Reports](../../issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) for currently tracked issues
 - See [Feature Requests](../../issues?q=is%3Aissue%20state%3Aopen%20label%3Aenhancement) for requested enhancements
 
 When filing an issue, please check for already tracked items
 
 Please try to include as much information as you can. Details like these are incredibly useful:
 
-* A reproducible test case or series of steps

 ## Development Environment
 
-This project uses [hatchling](https://hatch.pypa.io/latest/build/#hatchling) as the build backend and [hatch](https://hatch.pypa.io/latest/) for development workflow management.

 ### Setting Up Your Development Environment
 
-1. Install development dependencies:
+1. Install uv:
+
    ```bash
-   pip install -e ".[dev]" && pip install -e ".[litellm]

+   source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+   uv pip install -e ".[dev]" --prerelease=allow

+3. Set up pre-commit hooks:

    ```bash
    pre-commit install -t pre-commit -t commit-msg

 ### Pre-commit Hooks
 
-We use [pre-commit](https://pre-commit.com/) to automatically run quality checks before each commit. The hook will run `hatch run format`, `hatch run lint`, `hatch run test`, and `hatch run cz check` on when you make a commit, ensuring code consistency.

 ### Code Formatting and Style Guidelines
 
 We use the following tools to ensure code quality:
+
 1. **ruff** - For formatting and linting
 2. **mypy** - For static type checking
 
 These tools are configured in the [pyproject.toml](./pyproject.toml) file. Please ensure your code passes all linting and type checks before submitting a pull request:
 
 ```bash
 # Run all checks
-hatch fmt --formatter
-hatch fmt --linter
+python scripts/format.py
+python scripts/lint.py
 ```
 
 If you're using an IDE like VS Code or PyCharm, consider configuring it to use these tools automatically.
 
 For additional details on styling, please see our dedicated [Style Guide](./STYLE_GUIDE.md).
