[Arm-dev] CentOS 7.x images for ARM

Hi all,

Just saw CentOS 7.6 available for ARM. Cool.

Now, I had a look to isos/armhfp and saw different images.
Can anyone explain the differences between all images ?
-KDE- and -GNOME- look obvious, but what about -generic- and -RaspberryPi- ?
What about -RootFS- ?
Could it be possible to have a README or something to explain all that ?

Regards,
Stephan.
