L shaped desk with drawers (Plymouth)

I don't have the old documentation but I think it's a Realspace® Magellan Performance Collection L Desk, 30"H x 70 9/10"W x 23 1/5"D. I would need help disassembling it and moving it downstairs to be taken out, especially so you know how to reassemble it. The last time it was disassembled I remembered one of the slots being iffy if it would reassemble a third time correctly, so a note. It otherwise is a really nice desk.
