I have PiCorePlayer and LMS installed on a Raspberry Pi. When I connect to the Pi via my phone and the PiCoreplayer site I can see that PiCorePlayer and LMS are both running. When I connect to the Pi using Squeezer on my phone it shows the PiCore player but there's no music in the folder. Somehow LMS has not scanned the USB stick in the Pi. What do I need to do to make LMS on the Pi scan the USB stick to fill the music folder with music I can play ?

I have found the getting started stuff on the PiCorePlayer site incomplete and disjointed. Can anyone point me to a better, complete and joined-up getting started procedure for setting up PiCorePlayer and LMS on a Pi ?
