 This is the home of the android client library. It's mostly generated bindings
 via gomobile.
 
-To build you need to install android-ndk-r12b and build [Tensorflow for android](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/android).
+## Dependencies
+
+* android-sdk (and related tools)
+* android-ndk-r14b
+* android-platform-23
+
+To build you need to install android and build
+[Tensorflow for android](https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/android).
+You'll need to use the
+[luk-ai/tensorflow fork](https://github.com/luk-ai/tensorflow)
+and then run the commands below. Other versions of the NDK may work, but are
+untested.
+
+Commands to build Android dependencies:
