Set-up: Grasp two gymnastic rings with an overhand, shoulder-width grip. Make sure the rings are set high enough that your feet will not touch the ground at full hang.
Lift: A weight belt or weight vest will allow for external loading to make the exercise more difficult.
Emphasis: Bracing through your core, lift yourself up until your chin is over the bottom of the rings, trying to get as high as possible. Cue yourself to pull your chest to the rings to ensure full height. Descend all the way to full extension as this will engage more of the shoulder stabilizers and muscle mass of the back - this will help in maintaining health in the shoulder girdle.
Optional weighting: Grasp two gymnastic rings with an overhand, shoulder-width grip. Make sure the rings are set high enough that your feet will not touch the ground at full hang.
Assists: Do not swing your body up to the rings. It will change the movement pattern and should functionally be considered a different exercise. While useful in other contexts - swing and momentum are inappropriate here.
