While the Nexus 6X and 5X won't ship for another few weeks Google has already released the official Android 6.0 Marshmallow update to several devices. These have been released in the form of stock images hosted on Google's developer site. Some devices are receiving the update over the air. If you are using a custom recovery you won't be able to take the OTA update and will need to flash the update manually. "Rootjunky" has put together a modified stock image that includes a working flash-all.bat.

Google's stock images have to be flashed manually piece by piece. While doing this is not extremely hard it does require some steps which shouldn't be necessary. It is much easier to do a manual flash if you can just run the flash-all.bat. Rootjunky's modified stock image also includes a flash-all.bat that won't wipe your data. To use these you will need to have both adb and fastboot set up on your PC. This can be flashed over any firmware which means you can use this to flash to stock Marshmallow even if you are on a custom rom.

It should be noted that if you flash this stock image you will be on Android 6.0 Marshmallow, but you will have to reinstall a custom recovery if you desire and you will need to reroot if you want to have superuser access. Head to the link below, click on your device (nexus devices only), click on firmware, then select the mra59k build.
