+Non-Goals
+---------
+The focus of this project is on Android Jetpack and the Android framework.
+Thus, there are no immediate plans to implement features outside of this scope.
+
+A note on dependency injection - while many projects (such as
+[Plaid](https://github.com/nickbutcher/plaid)) use
+[Dagger 2](https://github.com/google/dagger) for DI, there are no plans to
+incorporate DI into Sunflower.  This allows developers unfamiliar with dependency
+injection to better understand Sunflower's code without having to learn DI.
