Remora cannot find upload_config.py

I've successfully flashed the firmware, but I cannot upload the config. Python packet tftpy doesn't include upload_config.py file. Is there any other way to do it?

In documentation it says - : "Your Remora config should be in this folder as well as the “upload_config.py” script. If they are not there you can find the script and sample configurations on the Remora github." 
But it's not there!

Does anyone has this script and can share.?

Edit. OK I've found it, but is buggy under linuxcnc 2.9.3, even if I had tftpy installed with pipx (globally) it could not find the package. On windows it cannot be run because of silly links to /tmp folder. I will rewrite it to make it run under win, hopefully tomorrow, today I've no more energy left after battling with it for a few hours.
