+### mobius-core [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-core.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-core)
+This is the core of Mobius, which all other modules depend on. It is a pure Java library that is completely self-contained. This is the only module that you need when using Mobius, because the others are optional extensions to the core.
+
+### mobius-test [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-test.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-test)
+The test module contains utilities that help you write tests for Mobius applications. It should only be used as a test dependency.
+
+### mobius-rx [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-rx.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-rx) / mobius-rx2  [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-rx2.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-rx2) / mobius-rx3 [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-rx3.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-rx3)
+The rx modules contain extensions for RxJava. You should use one of them in your Mobius applications since they simplify creating effect handlers and event sources. Both RxJava modules share the same API, the only difference is that one is built for RxJava 1.x and the other for RxJava 2.x.
+
+### mobius-android [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-android.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-android)
+The android module primarily contains classes for hooking up a MobiusLoop to Android.
+
+### mobius-extras [![Javadocs](http://www.javadoc.io/badge/com.spotify.mobius/mobius-extras.svg?color=blue)](http://www.javadoc.io/doc/com.spotify.mobius/mobius-extras)
+The extras module contains utilities and classes that help reducing boilerplate for some more advanced usage patterns (for example, nested update functions).

 ## Mobius in Action - Building a Counter
 
 The goal of Mobius is to give you better control over your application state. You can think of your state as a snapshot of all the current values of the variables in your application. In Mobius, we encapsulate all of the state in a data-structure which we call the *Model*.
