 ## Pre-commit
-We are using [`pre-commit`](https://pre-commit.com/) tool to perform checks on staged changes before committing. Such as black formatting.
-Depending whether you prefer to work ouside or inside Poetry virtual environment, you should stick to one usage or use both to still have this usefull checks.
-`pre-commit` can be used from the installation on your system or from inside Poetry virtual environment where it is installed.
+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, and `gitlab-ci` linting.
+
+Install `pre-commit` from your distribution. In case it is an outdated version, install it from `pip`:
+```bash
+sudo apt install pre-commit
+pip install --user pre-commit
+```
 
 To install the `git-hooks`, run:
 ```bash
-pip3 install --user pre-commit
 duniterpy> 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
+duniterpy> pre-commit run --all-files isort
+```
+To run all checks on all files:
 ```bash
-duniterpy> poetry shell
-(duniterpy-UyTOfZjU-py3.9) pre-commit install
+duniterpy> pre-commit run -a
 ```
