Use a drill to drill a hole in the wall where you'd like your deck to be hung. Then, insert a plastic wall anchor into the hole to ensure that it effectively holds the weight of the deck. Your deck display should come with a screw. Hold the display against the wall and line up the hole at the center with the hole you drilled in the wall. Use a drill or screwdriver to screw the screw into the wall through the hole in the display. Once the display is secured to the wall, twist the 2 bolts that came with the display on each of the posts sticking out from the display. Then, align the 2 screw holes nearest to the end of your deck with the posts and slide it on. Twist the 2 T nuts that came with the display onto either post until they're snug against the deck. This should securely hold the deck in place and keep any part of it from touching the wall.

Summary:
Drill a hole in the wall and insert a wall anchor. Secure your deck display to the wall with a screw. Twist the bolts towards the wall and slide your board onto the display. Twist the T nuts onto the display.
