+### Pre-commit hooks
+We are using [`pre-commit`](https://pre-commit.com/) tool to perform checks on staged changes before committing.
+We are using it for `fmt` formatting, `clippy` linter, `cargo check` and `gitlab-ci` linting.
+
+To install the `pre-commit`, run:
+```bash
+sudo apt install pre-commit
+```
+
+Install the hooks:
+```bash
+duniter> pre-commit install
+```
