-## Pre-commit
-We are using [`pre-commit`](https://pre-commit.com/) tool to perform checks on staged changes before committing.
-We are using it for `black` formatting, `isort` imports sorting, `pylint` code linting, `mypy` typing, licence headers and `gitlab-ci` linting.
-
-Install `pre-commit` from your distribution or install it from `pip`:
-```bash
-sudo apt install pre-commit
-```
-or
-```bash
-pip install --user pre-commit
-```
-
-To install the `git-hooks`, in the project folder, run:
-```bash
-pre-commit install
-```
-Then each time you commit changes, the hooks will perform checks.
-
-To manually run one of the tool above, run (eg for `isort`):
-```bash
-pre-commit run --all-files isort
-```
-To run all checks on all files:
-```bash
-pre-commit run -a
-```

 ### Authorization for GitLab CI linter hook
-`pre-commit run -a (gitlab-ci-linter)` is failing due to authorization required for CI lint API accesses.
+`make gitlab-ci-linter` is failing due to authorization required for CI lint API accesses.
 When running this command, just ignore this failed hook.
 In case you want to commit a `.gitlab-ci.yml` edition, this hook will prevent the commit creation.
 You can [skip the hooks](https://stackoverflow.com/a/7230886) with `git commit -m "msg" --no-verify`.

 We are using [Black](https://github.com/psf/black) formatter tool.
 Run Black on a Python file to format it:
 ```bash
-poetry run black duniterpy/file.py
+poetry run black path/file.py
 ```
-With `pre-commit`, Black is called on staged files, so the commit should fail in case black would make changes.
+With `autohooks`, Black is called on staged files, so the commit should fail in case black would make changes.
 You will have to add Black changes in order to commit your changes.
