Read these instructions.

First, check your bow to make sure that it does not have any cracks and that the string is fitted tightly. Second, select an arrow from the quiver. Once you have chosen an arrow, clip the end of the arrow onto the middle of the string. Turn to face the target. Keeping your back straight, pull the string back until it is almost touching your cheek. Next, sight along the arrow at the bull’s-eye at the center of the target. When you are ready, release the string.
