If you haven't already, you'll need to install Expo Go.
After that go ahead and clone the repo and install the dependencies. From your terminal run
# Clone the repo
git clone ...
# change into the directory
cd ...
# Install dependencies
npm i
Now you'll need to log in and head over to your dashboard on Instant and generate a new APP_ID. Open up src/App.js and replace the placeholder value to your new ID.
From there you should be ready to load up dev! From the project root
make dev
Huzzah!
