 This is a quickstart on how to use FirebaseUI's core features to speed up iOS development with Firebase. FirebaseUI includes the following features:
 
 ### FirebaseUI Core
-Provides core data binding capabilities as well as specific datasources for lists of data. Skip to the [Core API overview](https://github.com/firebase/firebaseui-ios#firebaseui-auth-api) for more information.

 ### FirebaseUI Auth
-Provides authentication providers as well as concrete implementations for Facebook, Google, Twitter, and Firbase email/password, plus a headful UI that handles auth state and error conditions.

-Note that `setup.sh` pulls in a number of provider frameworks (Facebook, Google), which need to be pulled in for local development. The build will also fail due to Google using `#import <Google/SignIn.h>` in their pod but `#import <GoogleSignIn/GoogleSignIn.h>` in the framework, so you can either change the imports, or include `FirebaseUI` in a Cocoapods project and edit there.
+Note that `setup.sh` pulls in a number of provider frameworks (Facebook, Google), which need to be pulled in for local development. The debug build and framework release have the flag `LOCAL_BUILD=1` which uses the local frameworks installed via `setup.sh`, while the Cocoapods release doesn't have this flag set, so the appropriate Pod `#import` statements are used.
 
 FirebaseUI makes use of XCode 7 features such as lightweight generics and `__kindof` annotations, but it should be backwards compatible to XCode 6 thanks to [XCodeMacros.h](https://github.com/firebase/FirebaseUI-iOS/blob/master/FirebaseUI/XCodeMacros.h).
