The anti static wrist strap is normally wrapped around your wrist . Attach the snap on the wire to the wrist strap if its removable, the alligator clip end goes to a good metal ground like the computer cabinet or a grounded work mat if you are working on laptops. The idea is that you discharge static electricity from moving around in a controlled fashion. My tip is: if you don't know what a good metal ground is do not work on your computer.
