how to run app.js

[stephanschulz]

Thanks for making your project public.

I followed the install steps on my RPI4. After running sh install.sh the PI rebooted and eventually the desktop shows. I assume to start the player I need to npm start or something?

But I am not able to make it run.

I did test that npm is installed with npm list and get:

cat /etc/os-release reports:
