This repo will contain Privategrity clients for all platforms.
+
+Preparation to Build
+==
+
+To build this client, you will need to get the Android SDK and NDK, and get and
+initialize gomobile. I recommend getting the Android SDK and NDK using Android
+Studio. Download it from https://developer.android.com/studio/index.html and
+follow the instructions to install it. I recommend choosing the Standard setup
+option.
+
+After running setup, at the Android Studio splash screen, click
+Configure-\>Settings towards the bottom. Navigate to Appearance &
+Behavior-\>System Settings-\>Android SDK, then SDK Tools, then check NDK. Click
+OK, follow the instructions, and before long you'll have an Android NDK
+installation.
+
+Export ANDROID\_HOME in your .profile or .bash\_profile, pointing to the
+location of your Android SDK installation. Then, after confirming that the
+environment variable change has taken effect:
+
+ $ go get golang.org/x/mobile/cmd/gomobile
+
+For Android support:
+ $ gomobile init -ndk=/path/to/your/ndk/installation
+
+On Linux, the NDK is in ~/Android/Sdk/ndk-bundle by default.
+
+For iOS support: TODO.
+
+In either case you will need to run $ gomobile init.
+
+Building
+==
+
+To build the .aar for the client, run
+
+$ gomobile bind
+
+Then import the .aar in Android Studio. For future builds, you'll need to copy
+the new bindings .aar over the .aar that's been imported to Android Studio.
