In one sentence, describe what the following article is about:

Most volleyball nets are secured to the ground through floor plates. Locate the holes in each floor plate, insert your Allen wrench, and twist the wrench until you pry the plate loose. You can buy an Allen wrench from most sports supply stores or online. Lift the pole up and insert it into the hole, holding it upright as you do so. As you lower the pole into the ground, it should click into place and stay upright without holding it.  Repeat this process with both poles. If the pole does not secure into the ground, the hole may be dirty or blocked. Remove the post and check for obstructions, removing any dust or debris as needed. Twist the volleyball poles at the bottom of the feet to raise or lower its height. If you need to make the poles higher than they can naturally go or your poles don't have adjustable feet, insert volleyball pole spacers at the bottom. The regulated net height for the following volleyball teams are:  Co-ed, standing disabled, or men's volleyball: 7 ft 11 inches (2.41 meters). Women's volleyball: 7 ft 4 inches (2.23 meters) Sitting or wheelchair volleyball: 4 ft 11 inches (1.5 meters) Senior volleyball: 7 ft 2 inches (2.1 meters) Children's volleyball: 6 ft 6 inches (1.98 meters) -7 ft 4 inches (2.23 meters) Locate the post hook on the lower half of each volleyball pole. Tie each side of the net rope to the post hook in a knot and thread the rope through the winch leader strap, a strap with a metal connector that hangs on the volleyball pole's side. Grab the winch, the handle jutting out of the pole's side, and turn it until the center of the net reaches the desired height. The center height should be match the regulation requirement for men's, women's, co-ed, or other volleyball groups. If you cannot reach the desired net height, try tightening the winch further or adjusting the pole height again. The volleyball net should have 2 additional net straps: 1 in the middle and 1 on the bottom. Grab the net straps and secure them to the hooks on each pole until the straps are horizontal and parallel to the ground. If you notice any excess rope from the net straps or net rope, loop it over the ropes and tie it in place. This will prevent tripping and injuries caused by the ropes while you play volleyball. Hold the ropes in place with loose knots to make removing the ropes simpler later on. Volleyball antennas mark the out-of-bound lines and help observers call fouls. Position the volleyball antenna over the net's top and secure it in place with a clip or other object, depending on the manufacturer. Although not necessary to play, volleyball antennas can keep the game fair.
Remove the floor plates with an Allen wrench. Place the poles into the ground. Adjust the volleyball poles to the required height. Attach the net rope to both poles. Tighten the winch to secure the net. Attach and tighten the net straps. Tie the ropes off to the end posts. Attach volleyball antennas to the net to spot fouls easier.
