I am installing onto a pi-0-w using the script provided on the Pi installation Page.

This page also mentions that due to limited memory on some models, its best to start using the `node-red-pi --max-old-space-size=256`

command.

So do i create a node-red-pi service to auto start node red with the system or is there an option for the default set up node red service?

If i need to define a new service can i use the node red .service file as a template ?
