+<p>The Android framework provides plenty of standard tools for creating attractive, functional
+graphical user interfaces. However, if you want more control of what your application draws on
+screen, or are venturing into three dimensional graphics, you need to use a different tool. The
+OpenGL ES APIs provided by the Android framework offers a set of tools for displaying high-end,
+animated graphics that are limited only by your imagination and can also benefit from the
+acceleration of graphics processing units (GPUs) provided on many Android devices.</p>
+
+<p>This class walks you through the basics of developing applications that use OpenGL, including
+setup, drawing objects, moving drawn elements and responding to touch input.</p>
+
+<p>The example code in this class uses the OpenGL ES 2.0 APIs, which is the recommended API version
+to use with current Android devices. For more information about versions of OpenGL ES, see the <a
+href="{@docRoot}guide/topics/graphics/opengl.html#choosing-version">OpenGL</a>
+developer guide.</p>
+
+<p class="note"><strong>Note:</strong> Be careful not to mix OpenGL ES 1.x API calls with OpenGL
+ES 2.0 methods! The two APIs are not interchangeable and trying to use them together only results in
+frustration and sadness.</p>
