How to add ads to android application?

Question

Android

I recently started learning Java and decided to try to develop programs for Android.
One of my first free programs suddenly hit the top and got a lot of good reviews. There are 100 - 200 installs per day and almost no deletions.
I decided - well, since such a booze has gone, maybe I can somehow monetize it ...
But the trouble is - I can’t google clear and up-to-date instructions on how to add a Google ad block in Android Studio.
Please point me to the right place in the documentation in Russian.

Admob https://developers.google.com/admob/android/quick-start
firebase - https://firebase.google.com/docs/android/setup
Both now belong to Google, they have integrations. You can customize the look of the ad.
