I don't have enough posts to change the WIKI but this is the current story at ATL:

Global Entry kiosks are on the left wall as you enter the immigration area (the queues for the non-GE are to the right). After completing with the kiosk (facial recognition, no reset), continue to the far side of the room and turn right for the GE exit booths. Your face will be matched visually by the agent (against a line up of those recently through the kiosks) and you proceed to baggage claim. If you have no problems with your connecting flight (and no reason to open the bags) move them over to the drop off belt. There are two queues at security. Sometimes one is set up as TSA Precheck, sometimes they are both regular. Amusingly, when they have a Precheck line, there's usually nobody in the other one.
