 1. From the root directory of `lifelines` activate your [virtual environment](https://realpython.com/python-virtual-environments-a-primer/) (if you plan to use one).
 2. Install the development requirements and [`pre-commit`](https://pre-commit.com) hooks. If you are on Mac, Linux, or [Windows `WSL`](https://docs.microsoft.com/en-us/windows/wsl/faq) you can use the provided [`Makefile`](https://github.com/CamDavidsonPilon/lifelines/blob/master/Makefile). Just type `make` into the console and you're ready to start developing.
