Where can I find comprehensive documentation?

Where can I find thorough documentation on angular/fire? I first started using angular/fire about 2 years ago. Super confusing. The articles on the web are all over the place, mixing compat with the current model, some saying stay on compat (assume they were old articles), some intermixing angular/fire with straight google firebase calls (which this library is supposed to wrap, correct?). Even this site sends the user back to the google firebase side. Because of this, as a newbie a couple of years ago, I ended up intermingling my code, sometimes using angular/fire/compat, mixing in angular/fire, and other times importing straight from firebase. I eventually "got it", but again, super confusing.

So, now I am replacing my old v6 compat with the new model, but I cannot find simple documentation. The md's on this site are minimal. Is there a place that I am just over looking that is a good source for angular/fire documentation.

Thanks!

この issue では、特定のファイルやテストは指定されていません。まず既存の AngularFire Markdown ドキュメントを確認し、compat と current-model に関する説明を Firebase ドキュメントと比較してください。v6 compat からの移行方法と、AngularFire の import と Firebase の直接呼び出しを区別する方法を明確に示す情報源があれば完了です。
