 ReactiveAndroid
 ===============
 
-Demo app showing reactive development usage in Android along with Lambdas.
+This is an experimental Android app. It shows reactive programming paradigm by using RxJava from Netflix. To make coding
+more pleasant, it uses Lamdas from Java 8. The app pulls the content from [Rotten Tomatoes API](http://developer.rottentomatoes.com/ "API").
+Please use this link and register to get your own developer key. It is needed to run this demo app.
 
+Place the key under src/main/res/values/key.xml (or any other name). key.xml is already added to .gitignore so it will
+save you some work.
 
-This is the intial unclean version. You need to have mashery key for rottentomatoes.
+Here is what the contents of key.xml look like:
+
+<?xml version="1.0" encoding="utf-8"?>
+<resources>
+    <string name="ROTTEN_KEY">YOUR DEVELOPER KEY</string>
+</resources>
+
+
+In progress:
+
+The work in this app is still in progress. I want to also demonstrate usage of Dagger, Otto(?) and couple more
+useful libraries.
