Help Installing ROCK on a Azulle i5 Kaby Lake Mini PC

I have already successfully configured an Intel NUC. Now I am trying something different. But I have a couple of issues:

  1. I want to configure an Azulle i5 Kaby Lake Mini PC to run ROCK.
  2. I am trying to download the ROCK install image but it is downloaded as a .img and not .gz file. Here is the filename of the download I am getting: roonbox-linuxx64-nuc3-usb-factoryreset-100000227.img . . It doesn’t have a .gz extension.
  3. What is the process in installing the appropriate image on the above Azulle?
    Regards, RJ
