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!

该 issue 未指定具体的文件或测试。首先查看现有的 AngularFire Markdown 文档，并将其中关于 compat 和 current-model 的指导与 Firebase 文档进行比较；当存在一个能够清楚说明如何从 v6 compat 迁移，以及如何区分 AngularFire import 与直接调用 Firebase 的来源时，即表示完成。
