This document provides an overview of programming basics for Google Glass. It describes the basic operations and interfaces of Glass like the power button, touchpad, voice commands, and winking. It also covers getting started by setting up an account and installing the MyGlass companion app. Finally, it discusses the two main APIs for building Glassware: the Mirror API for platform-independent apps and the Glass Development Kit (GDK) which allows access to hardware and offline functionality through an Android SDK.
