mainsailos on Raspberry Pi 4 does not have confiug files

[nickr1957]

Using Pi Imager and the KlipperPi latest installation, the Pi does not respond to a browser request.
I can SSH into it, but the klipper_config folder described in the instructions here does not ecist.
In klipper->config there are many example files but nothing for FLSun and once again there is a list of a range of robin boards - the reason I was trying this klipper version was because I expected not to have to try to identify exactly which board to use.
It seems that is not possible.

Am I missing sometjhing? Do I have to go through the long-winded Balena process and all that config and will that install with the folders mentioned here?
