It is kind of awkward at first lol
Set the rack at your normal squat height. Then walk into the barbell without ducking under it to put the bar on your back. The barbell should hit you right in the front delts. Then bring your right arm up, cross it over to put your right hand on your left shoulder. Raise your left arm up, cross it over and put your left hand on your right shoulder. The action with your arms will raise your delts slightly and sort of plop the barbell right in the natural place. My hands are usually very lightly on the bar itself. For me, getting the bar in the right place makes your delts act kind of like a shelf.
You might have to fiddle with position some (that's what she said

) but it doesn't take long to figure out.
