Cloud Firestore -> Rules -> allow read, write must be set to "true"

[S-Burns]

The github download has the following issue

When configuring Firebase, "Database", in the "Cloud Firestore" Dropdown, "Rules"
has read, write set to "false" and creates a 'Missing or insufficient permissions.' notification, unless set to "true"

service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}

I had an entire evening of headaches until I read this. Thank you! The README.md should be updated. This was the only other thing that I had to do in order to get it running properly as is.
