+## Linting
+
+The package uses [ruff](https://docs.astral.sh/ruff/) for linting,
+with both a [pre-commit hook](./.pre-commit-config.yaml)
+and a checking step in the [package build GitHub action](./.github/workflows/python-package.yml).
+Checks should use `ruff`'s [default rules](https://docs.astral.sh/ruff/rules/)
+except from line length (specified in [`pyproject.toml`](./pyproject.toml)).
+A [plugin](https://github.com/astral-sh/ruff-vscode) is also available for VSCode.
