+### Code style & formatting
+
+We use `pyink` to format Python code (with 2-space indent) and `isort` to sort
+imports to match Google standards. To automate this and ensure your changes
+pass CI lint checks:
+
+1.  **Install pre-commit** (if not already installed):
+    ```bash
+    pip install pre-commit
+    ```
+2.  **Install the git hooks** in the repository:
+    ```bash
+    pre-commit install
+    ```
+
+Once installed, `isort` and `pyink` will automatically run on and format
+any files you modify whenever you run `git commit`.
+
+If you prefer to run them manually without committing, you can use:
+```bash
+pixi run -e tests isort --check .
+pixi run -e tests pyink --check .
+```
+(Or specify individual files to check instead of `.`).
+
 ### Running tests
 
 The Xee integration tests only pass on Xee branches (no forks). Please run the
