You must be talking about the goblet squat....Kettlebells are primarily used for ballistic movements engaging mainly the posterior chain muscles (glutes, hamstrings, back). swings, snatches, and clean and presses are good to start out with.
Kettlebell movements also require ALOT of form and coordination, so simply reading about how to do an exercise might not be enough to master the movement(s). Talk to an RKC or HKC instructor...if you don't have access to one, you can also try searching on youtube: turkish getup, goblet squat, kettlebell swing, kettlebell snatch
youtube has some great tutorials on kettlebell movements, but I would still get a second opinion from a professional to avoid injury if I were you.
hope this helps!
