Just unpack and dd it on to an SD card. This assumes an RPI3 with the official 
7" touch screen connected via DSI, it might work in other configurations but 
that's untested. It should boot directly into a Plasma Mobile shell.

Give it a bit to settle after startup before judging performance, once things 
are running it's much smoother than the very first impression.

Notes on the configuration:
- portrait mode is disabled due to causing various visual glitches, which 
however results in a rather small workspace. Portrait mode can be enabled for 
testing in config.txt on the boot partition by adding the following two 
settings:
dtoverlay=rpi-ft5406,touchscreen-swapped-x-y=1,touchscreen-inverted-x=1
display_rotate=1
(the first line replacing the existing entry for rpi-ft5406)

- serial terminal is disabled, as that conflicts with Bluetooth and affects 
dynamic frequency scaling. If you need it for testing, add the following to 
config.txt:
- enable_uart=1
- dtoverlay=pi3-disable-bt
and extend cmdline.txt by "console=serial0,115200"

The default user account is kde/kde (you'll need that if the screen lock kicks 
in), SSH is enabled too, the root account has no password set.

Let's discuss at Akademy how to proceed from here :)

Regards,
Volker
