Crooked garage door is driving me up the wall

Both my garage doors are crooked,  causing one side of each door to have a gap at the bottom. What info do I need to supply here to get an idea of where to start adjusting? 

What I do know is that there's a Clopay EZ-set item that the braided cables feed in and out. I have electric openers attached to each door.

And yes, I typed "crooked" into the search, but there were no results....

... which I think is weird because I can't be the only one that this has happened to.

Kindly add some images or videos of your garage door to understand better. I also need other information like the specific Clopay EZ-set model, age of the door and opener. 

Which part of the door is higher on each side? Is it the top hinge side, the middle part, or the bottom hinge side?
Do the cables seem loose or unevenly tensioned?
Do the hinges appear damaged or misaligned?
Do the doors ever make unusual noises while opening or closing?
