 ### User Interface
 
-This layer makes use of the Android Framework and is used to create all of our UI components to display inside of the [Browse Activity](https://github.com/bufferapp/android-clean-architecture-boilerplate/blob/9a1308c42c0c882fc724a0e579ee1ce4d454f961/mobile-ui/src/main/java/org/buffer/android/boilerplate/ui/browse/BrowseActivity.kt). The layer receives its data from the Presentation layer and when retrieved, the received models are mapped using the [Bufferoo Mapper](https://github.com/bufferapp/android-clean-architecture-boilerplate/blob/9a1308c42c0c882fc724a0e579ee1ce4d454f961/mobile-ui/src/main/java/org/buffer/android/boilerplate/ui/mapper/BufferooMapper.kt) so that the model can be mapped to this layer's interpretation of the Bufferoo instance, which is the [BufferooViewModel](https://github.com/bufferapp/android-clean-architecture-boilerplate/blob/9a1308c42c0c882fc724a0e579ee1ce4d454f961/mobile-ui/src/main/java/org/buffer/android/boilerplate/ui/model/BufferooViewModel.kt).
