Use the square TroGlass lettering cutout to mark where to drill holes in your wall. Next, use an electric drill or screwdriver to drill the mounting screws (in the standoff kit) into the marked places on your wall.
Once the holes are drilled, mount the standoffs. Finally, hang the square cutout and the lettering cutouts (in that order) on the standoffs. Finally, secure the acrylic lettering to the standoffs with an Allen key.
