+## Formatting and linting
+
+The easiest way to run the formatting and linting is to use the [pre-commit] tool.
+Install it, then run:
+
+```bash
+pre-commit run --all
+```
+
+This will run formatting and linting on all files in the repository (principally using [ruff]).
+
+To install as a pre-commit hook:
+
+```bash
+pre-commit install
+```
+
+## Managing the Python code
+
+The pyproject.toml follows the [PEP621] standard.
+To install all dependencies you may use [uv]:
+
+```bash
+uv sync --all-groups --all-extras
+```
+
+A Makefile exits to execute some common tasks:
+```bash
+make docs-html
+make docs-linkcheck
+make format
+make lint
+make test
+make test-matrix
+```
+
+The test matrix is executed using [nox] and runs all tests in all supported Python versions.
+The Python versions must be pre-installed on your system.
