+# Contributing Guidelines
+
+First off, thanks for considering to contribute to this project!
+
+These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
+
+## Git hooks
+
+We use git hooks through [pre-commit](https://pre-commit.com/) to enforce and automatically check some "rules". Please install them (`pre-commit install`) before to push any commit.
+
+See the relevant configuration file: `.pre-commit-config.yaml`.
