Dig two holes into the ground 5 feet apart. Make the holes 6 inches around and 12 inches deep. Place the posts, one into each hole, into the ground. Use the leveler to ensure they are sitting straight. Pour the dry cement mixture into the holes over the posts. Add enough water per concrete package specifications to the holes and allow them to set for 1 hour. You do not need to mix the concerete.
Set the two 2-inch-by-6-inch-by-6-foot boards onto the ground 4 inches apart. Set the eight 2-inch-by-4-inch-by-2-foot boards over the 6-foot boards at equal intervals. Use the measuring tape to set the two end pieces in 4 inches from the edge, then set the inside boards on every 8-inch mark from the ends. Tighten each one with two screws on each side.
Lift the canopy piece onto the posts; the outer 2-inch-by-4-inch-by-2-foot pieces should rest just within the 4-by-4 posts. You will need assistance holding the canopy in place while it is being secured.
Drill three screws into the 2-inch-by-6-inch-by-6-foot boards on each side of each post. You will have drilled six screws onto each post, 12 altogether.
