 A Dart wrapper for [Firebase](https://www.firebase.com).
 
 This package contains two implementations of the same ```Firebase``` Dart API:
-* The ```JsFirebase``` implementation uses `dart:js` to wrap functionality provided by `firebase.js`
+* An implementation that uses `dart:js` to wrap functionality provided by `firebase.js`
 in Dart classes. You'll need this implementation to build Firebase apps for the web.
-* The ```MojoFirebase``` implementation uses [Mojo](https://github.com/domokit/mojo) to wrap functionality provided by Firebase iOS and Android SDKs. You'll need this implementation to build Firebase apps with [Flutter](http:/flutter.io).

-Right now the ```MojoFirebase``` implementation is default, but you can change this in lib/src/firebase.dart. Once [dart-lang/sdk#24581](https://github.com/dart-lang/sdk/issues/24581) is fixed you'll get the right implementation automatically.
