firstly hello to all

i have just got biab and sat all last night in front of the monitor wondering what to do and how to do it. please can some one tell if there is a tutorial which takes you from the start and shows you how to use biab , i have had a look on youtube but they start from a level which at the moment is above me and they use real band instruments, this is what i want to do but it appears i have none, or do i ? but i have areal band icon on my desk top.
thanks tj
