App crashes when I change the firebase

[TimRivoli]

I created my own firebase and downloaded the google-services.json file for it. Now the app crashes when it tries to start. It works fine if I change it back to your firebase. What do I need to do to get it to work with a new firebase setup?

You need to create index in firestore, I'll update config step in README.md as soon as possible.
