 The debug drawer is something you can add to your debug builds to make your life easier as a
 developer or tester. It provides a convenient way of exposing development specific controls without
 cluttering up your user interface. There are quite a few possibilities this opens up, such as adding

 This repository provides two sample apps that demonstrate usage of the debug drawer. The
 `simple-sample-app` has no other dependencies and is about as bare-bones as you can get. The
 `sample-app` is a bit more complex. It interfaces with the
 [Giant Bomb API](https://www.giantbomb.com/api/) to retrieve and display a list of video games, and
 aims to be closer to a real application.

+Browsing through the implementation of `sample-app` should provide you with an idea of how you could
+add the debug drawer to your app. You might want to use dependency injection to assist in setting it
+up, or you could follow the example and try and roll something by hand. Whatever your choice, it
+doesn't need to be particularly complex.
