 - Make sure you have the `firebase.json` file in the repository
 - Get the Firebase token by running `firebase login:ci` and [store it](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets) as the `FIREBASE_TOKEN` secret
 - Set the project name in the `FIREBASE_PROJECT` env var
