How to fold tonneau cover?

Such a stupid question, I'm sure I'm just missing something obvious. The dealer "installed" the lightweight folding tonneau cover for me when I took delivery. That was all well and good until I went to take a load of cardboard that had been building up to the recycling center. I could not figure out how to fold the tonneau cover! The instructions on the bag made me think you twist this then flip that and viola! But it never really seemed like the shapes were coming out right. My wife and I struggled with it for entirely too long (15 min maybe?) and I even googled it but of course came up with a bunch of truck stuff. At this point I feel so stupid, I'm going to probably need a video or at least some clear pictures of what it should look like midway through and at the end. I can twist it then sort of fold it where I'm sure I can get it into the bag, but it doesn't look right and I don't want to force it into a shape the wrong way 'round.

Thanks, sorry I'm stupid....
