 ## We Develop with Github
 We use github to host code, to track issues and feature requests, as well as accept pull requests.
 
+## Quick Setup
+To set up the development environment, run the following commands in the root of the repo:
+```cli
+make setup
+source ./venv/bin/activate

 ## Dependencies
 To install the dependencies for developing and updating the code base, be sure to run `pip install -r requirements-dev.txt`
