FireStore Rules - Firebase

Question

Does the following rules mean that every collection is readable and writable if user is authenticated EXCEPT of the "cities" collection (city field). cities/city is readable but not writable at all. is this description right?

rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
match /cities/{city} {
allow read: if request.auth != null;
allow write: if false;
}
}
}

Answer 1

If you want users not to write to your database in the path /cities, remove the "if" and leave the "false" one, so no one will write to this database, they will only read whoever is authenticated, and I recommend reinforcing the rules because whoever is authenticated can write to the other's datas
