I have been looking around many different places for how to implement notification sending using cloud functions. And the best I have found is the following: Push notifications using Firebase Cloud Function iOS
But I believe it would benefit many people as well as me, if this fragmentation were fixed with one set of instructions from start to finish.
Thus I ask: How can I implement notification sending when a user creates something at a certain spot in firebase realtime DB?
From start to finish, a very clear explanation for someone doing this for the FIRST TIME.
