 # Development environment
 
 To set up your development environment make sure you have valid version of
-Python (check `pyproject.toml`) with [Poetry](https://python-poetry.org/)
-installed on your `PATH` and then do the following in the root of the
-repository:
+Python (check `pyproject.toml`) and a `virtualenv`.
+
+Use your favourite way of setting up a `virtualenv`, e.g.:
 ```
-poetry install  # Install dependencies.
+mkvirtualenv -a `pwd` looper -p /usr/bin/python3.10
+```
+
+Or simply use `venv` module directly:
+```
+python3.10 -m venv .venv ; source .venv/bin/activate
+```
+
+After `virtualenv` has been created and activated, continue with the following:
+
+```
+pip install -r requirements_dev.txt  # Install dependencies.
 cp looper_example_project/settings.example.py looper_example_project/settings.py  # Adjust settings.py as needed.
 # Make sure you have your database setup according to your settings.py
-./manage.sh migrate  # Update the schema.
-./test.sh  # Make sure the tests run.
+./manage.py migrate  # Create database tables and run migrations.
+./manage.py test  # Make sure the tests run.
