Fauna 21T tool offsets and work offsets

Looking for some help...Not new to machining, but somewhat new to CNC. I have a "new to me" 2 axis lathe up and running with a 21T controller, and trying to learn how to set up tool and work offsets.Can anyone provide a logical step by step how to?...or direct me somewhere that can?? I have the Fanuc manual, but it's not really clear to me.Appreciate any help!Thanks,Todd
