Yes it’s easy to set up. It comes with simple directions that you should be able to follow. If there are an issues there is plenty of help here on this forum.
It runs Roon Server and you need to control it from another device somewhere else on your network. That can be an iPad ( not the older ones) or an andriod tablet or you Mac mini if it has a screen and keyboard. You also use smartphones as your control device but they are a bit small and don’t do everything the other remotes do.
