Minor change

[RoYoMi]

I had to use slightly different installation instructions:

Instructions said: git clone git@github.com:skhg/juice4halt.git
I found that would throw an error about not being authorized
Used this instead git clone https://github.com/skhg/juice4halt.git

The watchdog service didn't start directly after install, so the systemctl status juice4halt showed errors
After rebooting the device, the watchdog service started, and the status command ran as expected.
Recommend future users either manually start the watchdog process or issue a reboot.
