+## Developing with the template

+To develop the template for your own project, you'll need to make sure to [create your
+own repository from this template](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/creating-a-repository-from-a-template) 
+and then install the project's development dependencies. You can do this with:

+pip install -r requirements/develop.txt
+```

+This'll install some style formatting and testing tools (including `pytest` and 
+`locust`).
