When I use the word "drift" people get bent out of shape so I refer to it as "Skid".
To learn to drive while skidding require basic driving before skidding.
Asc is going to help you learn without destroying your car from roll over or excessive power slide.
Pedal brake - Can be used to oversteer.
E-Brake - Can be used to control lateral skid.
Throttle - Can be used to under-steer or over-steer.
Steering - Very important while skidding. While it help to gain muscle memory for degree of turn & speed. Limiting your steering angle will help with alot of things.
Tip & tricks:
I started out trying different things with steering input, spent more time thinking about how to free my right hand for gear shifter & e-brake.
How to initiate the turn-in steering input to free my right hand & still effectively use the steering wheel & angle.
I dont think you can teach these things, you'd have to experience it first hand.
You need to be comfortable with the lateral weigh transfer while keeping your steering wheel angle relative to your actual wheel angle.
Once you try to drive fast thru corners you will eventually figure it out.
I take it +1mph at a time when I was feeling out my RA. 30mph turn no brakes, 31mph turn no brakes, i hope you get the picture.
