How to authenticate using Firebase Authentication in Ionic-4?

I am looking for a tutorial on how to include Firebase Authentication Ionic-4? I have been searching the same on this forum but dont seem to find an answer?

It seems like since the Ionic team has started enterprise support they kind of have given up on the community?
