+### Summary
+
+This app uses the Model-View-Intent architecture and uses RxSwift to implement the reactive characteristic of the architecture
+
+The MVI architecture embraces reactive and functional programming. The two main components of this architecture, the _View_ and the _ViewModel_ can be seen as functions, taking an input and emiting outputs to each other. The _View_ takes input from the _ViewModel_ and emit back _intents_. The _ViewModel_ takes input from the _View_ and emit back _view states_. This means the _View_ has only one entry point to forward data to the _ViewModel_ and vice-versa, the _ViewModel_ only has one way to pass information to the _View_.  
+This is reflected in their API. For instance, The _View_ has only two exposed methods:
