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!

該 issue 未指定特定的檔案或測試。先檢視現有的 AngularFire Markdown 文件，並將其中關於 compat 和 current-model 的指引與 Firebase 文件進行比較；當有一個能清楚說明如何從 v6 compat 遷移，以及如何區分 AngularFire import 與直接呼叫 Firebase 的來源時，即表示完成。
