+## Checking your code locally
+
+### By hand
+
+You can run flake8 with tox to verify the quality of your code. For that you
+can simply call tox with that command:
+``` console
+$ tox -e lint
+```
+
+If you tox is missing on your environment you can probably install it through
+your package manager (Eg: `sudo apt install tox`) or with pip (within a
+virtualenv):
+
+``` console
+$ python3 -m venv .venv
+$ source .venv
+$ pip install tox
+```
+
+### Automatically for each commit
+
+This repo contains some pre-commit configuration to automatically check your
+code foreach commit. To use that configuration you should "install" it by
+running:
+
+``` console
+$ pre-commit install
+```
+
+Then autoflake, flake8, isort and codespell must run when you add some commits.
+You can also force them to run with this command:
+
+``` console
+$ pre-commit run --all-file
+```
+
+If pre-commit is missing on your system, you can install it (on Debian based
+system) with `apt`:
+
+``` console
+$ sudo apt install pre-commit
+```

-    - When C(true), the C(query_all_results) return value
-      contains only the result of the last statement.
-    - Whether the state is reported as changed or not
-      is determined by the last statement of the file.
-    - Used only when I(path_to_script) is specified, otherwise ignored.
-    - If set to C(false), the script can contain only semicolon-separated queries.
