 ## Development Information
 
+To start developing, install the development dependencies and pre-commit hooks:
+
 ```bash
-pip install .
+pip install ".[dev]"
 pre-commit install
 ```
+
+There are several [pre-commit hooks](https://pre-commit.com/) that will run on every
+commit to perform formatting, typing, and linting.
+
+* `ruff` - Runs formatting, import sorting, and linting.
+* `mypy` - Runs type checking.
+* `markdownlint` - Runs markdown linting.
+* `yamllint` - Runs YAML linting.
