+Replace `<make-args>` with any arguments you want to pass to `make`, and then execute the
+`assembleDebug` or `installDebug` task corresponding to the hardware platform you are targeting.
+For example, to deploy to a Nexus 9, which runs the AArch64 architecture, execute `installArm_64Debug`.
+A list of available tasks can be found in Android Studio in the Gradle tray, located at the top-right
+corner of the IDE by default.
 
 The native libraries will be compiled, and copied into `./Source/Android/app/libs`. Android Studio
 and Gradle will include any libraries in that folder into the APK at build time.
