Drill a hole in the base of the guitar neck on the side facing away from you when you hold the guitar to play. The hole should measure about 3/32" in diameter and should be about 3/8" to ½" deep and screw in the second strap peg. As an alternative, you may want to have someone at a music store install the hole for the pegs.
Find the two pins or knobs on your guitar. There should be one near the neck and one at the bottom of the guitar body.
Find the small slits on each end of the guitar strap.
Push the guitar strap over the knob on the guitar to fasten the guitar strap.
