How do I properly use the launch control feature in my 2002 BMW m3 with SMG?

I just purchased a bmw m3 with smg.
I heard that this car has launch control, a bit limited in US, but its still there. Does anyone know how to use this? I have the sport button, smg control, and a dsc button. Also have the paddle shifters, and am driving pretty good with them now.
Also, I understand that this may be bad for the tranny, but I still want to know how to do it.
Thanks to all!
