 ## Development setup
 
-* Install [poetry](https://python-poetry.org/docs/#installation)
-* Run `poetry install`
-* For basic style checks setup [pre-commit](https://pre-commit.com) by enabling it (run
-  `poetry run pre-commit install`).
-* To run cli tools, e.g.: `poetry run msh2vtu`
+Create a virtual environment, activate it and install required packages:
+
+```bash
+python -m venv .venv
+source .venv/bin/activate # run this in every new shell session
+pip install -e ".[test]"
+
+# enable basic style checks once:
+pre-commit install
+```
+
+CLI scripts can now be simply run:
+
+```bash
+msh2vtu --help
+```
