Snap, I'm at the hospital all day today with my dad, but you can call me on Tuesday and I'll walk you through it. It's not hard, but it's not that unsimilar to V-brakes. Same concept, but put your hand over the tire, squeeze the two brake pads together down all the way onto the rim, then pull the tab on the cable to get the other tab out of the "hook".

Check the centering when you put it all back together.
