+  The Android M platform is still under development, but we’re offering developers an early look
+  through the Android M Developer Preview program. This program is an opportunity for you to test
+  the compatibility of your apps with the next platform release, try out early versions of new API
+  features, and provide feedback to the Android team. Developers can try out the M Preview system
+  on with the Android SDK emulator or on Nexus 5, Nexus 6, Nexus 9, and Nexus Player devices. The
+  program includes update releases during course of the program to allow you to follow the progress
+  of feature development and fixes, leading up to the official release of the platform.
