How do I set up FirebaseDB?

I want to use Firebase for the server for my app, but I have no idea on how to set up the component. I did make a project in Firebase Console, now how can I connect it with my app?

I do not know what topic or post to look at, can you point one out or tell me how to do it?

This discusses the FirebaseDB component

and this is the component's documentation
