+Development setup
+-----------------
 
-After setting up your virtual environment, install development dependencies:
+* Set up a Python virtual environment with `python -m venv venv` at the root of this project.
+* Run `make dev` to install the project in editable mode and install dependencies.
 
 ```shell
-$ pip install -r requirements-dev.in
+$ python -m venv venv
+$ make dev
 ```
 
+The Makefile is already configured to use Python from the virtual environment `venv`; for running other commands, activate it using `source venv/bin/activate`.
