The posts on either side of the deck act as the support beams for the pergola (Image 1). Hang a crossbeam from these posts, checking level as you work (Image 2).
Attach a ledger board onto the side of the house (Image 1) 6 inches higher than the cross beam, so that the shade members will rest on the cross beam and sit in joist hangers on the ledger board. Attach your joist hangers (Image 2), using a joist jig for consistent size, every 6 inches on center.
Cut your shade members to size and hang them into the joist hanger, and resting on the crossbeam (Image 1). Toenail the shade members into the cross beam to secure. When all the shade members are installed, cut crossbeams that will rest on top of the shade members (Image 2).
