+# Sync user preferences across devices
+
+This application illustrates how to implement user preferences with Syncbase.
+The user logs into a trusted 3rd party -- we use Google auth, but it could
+be any cloud or nearby service that uses identityd to provide a blessing.
+
+Then when devices are offline and in physical proximity or connected via
+any network path, the user preferences will sync.
+
+# Building and running
+
+From the command line, you can build and install
+on the Android emulator or a device with the following command:
+
+    ./gradlew installDebug
