This pattern is worked top-down meaning you'll start by making the back yoke at the shoulders, and work your way down until the armholes. You'll then cut and reattach your yarn at the shoulders and work the front yoke until the armholes. From there, you'll work in turned rounds until your top is as long as you'd like. There are no right or wrong sides to the top until you've worked a border at the very end. The benefit of working top-down is that you can try your top on as you go and make it as long or as short as you'd like!
