OSMC settings

do you have tutorial for setting osmc on raspberry pi 3
live tv and so on
OSMC is installed via NOOBS

There is no complete Tutorial showing everything but the WIKI and also this forum should have most information covered. And for many things (Samba, TVHeadend and Transmission) you have Apps in the App Store that do most work for you automatically.

Just a side note, if OSMC is the only OS you want to run it is recommend to do an install via the OSMC Installer instead of NOOBS.
