I think it was already mentioned, run a search. But here is a vague memory of what I’ve remembered.

You unscrew them from the bottom and take out the mud flaps as well. Then you slide it a little and it should come off, don’t remembers which way though but you'll get the feel for it. The reverse you pop out the latch grommets (wherever you call them) off the car and slide them back on the skirt individually and snap in the entire skirt back onto the car. You might have trouble lining up the grommets, use cheap glue to temporarily hold them in place so you can pop them on.

hope that helps
