Roon Rock and NUC models

I have a NUC that is set up and ready to go. How do I get my iPad and NUC to talk to each other?

Load the Roon app on your iPad, then connect to your Roon core.

Right, if you Roon Core is up and broadcasting to your network then your iPad’s Roon application will pick it up as a core option, then from the iPad you can select and configure it.
