You'll need to connect your Raspberry Pi to a display (TV, monitor, etc.) along with a keyboard and mouse to set things up in Media Center like Media Network, along with importing your media (and mount any drives, e.g. a NAS, to the Pi if needed) before you'll be able to use a remote like JRemote, Panel, MO 4Media, etc. It isn't a plug SD card into Pi and use right away type of solution, it does require setting up and configuring things.
