To add to what onederlnd advised, I suggest that you list the formal education that you have completed as well. If you have taken any computer science courses in your high school, these may be beneficial for you to add as well to emphasize your interest and experience in the information technology field. Anything else that shows that you are a responsible and caring person would be great as well. List any non-technical volunteer work also that shows that you are not only interested in a job for money, but for more experience as well as because you enjoy it.
