+We are using `pre-commit <https://pre-commit.com/>`_, there is a :file:`.pre-commit-config.yaml`
+pre-commit config file in the root's project.
+
+You need to:
+
+- install the pre-commit library::
+
+    pip install pre-commit
+
+- registrer the pre-commit git hooks with this command::
+
+    pre-commit install
+
+- launch the quality code procedure with::
+
+    pre-commit
+
+  or simply just commit your changes, pre-commit will automatically be launched.
+
+.. attention:: If an error is found, the commit will not happen.
+   You must resolve all errors that pre-commit that pre-commit points out to you before.
+
+.. note:: If you need for some reason to disable `pre-commit`, just set
+          the `PRE_COMMIT_ALLOW_NO_CONFIG` environment variable before commiting::
