 ### Things to know:
 
-- Python3.10
+- Python3.11
 - Use [Poetry](https://python-poetry.org/)
 - Launch tests with `pytest`, config is in setup.cfg
 - `black`, `isort`, `flake8` and once mypy will work with 3.10, we'll use it. There's `pre-commit`, so you can install hooks with `pre-commit install`.
