Android M for Nexus 5, 6, 9 and Nexus Player are already available for download, in the form of developer preview images.
Earlier today, we reported about the official Android M announcement.
You can download the Android M Developer Preview System Images for the following devices.
- Nexus 5 (GSM/LTE) “hammerhead”

Here is the official download page for the Android M system images.
Google will provide OTA updates (Over-the-air) from time to time. The OTA updates will be available to a device once you flash the preview onto it. Google will also provide new system images too. You can flash the images using adb, but do take a backup of your data before flashing the new version.
