Anxious to give Android M a whirl? The developer preview is currently available, and you can get it at the source link below for the Nexus 5, Nexus 6, Nexus 9 and Nexus Player. But proceed at your own risk. Early previews like this have a tendency to be all sorts of wacky. Instead, if you use a Nexus phone as your backup device, or you’re simply the bravest person alive, you can get Android M up and running now.

Not only does Google provide the necessary files, but it also provides support, and directions on how to get Android M installed. We already installed it on a Nexus 5 here in the office, and we’re noticing a lot of subtle differences. Many of the big new features are happening under the hood; things like Doze, runtime permissions and other power-saving features. But there are many, many more features, so check out this list to see what else to expect.
