 Before you start creating the items for your references or bibliography, you need to select a citation style. Keep in mind that you can change this whenever you need to. It's not a permanent thing. Go ahead and select Edit. From your toolbar, then choose Preferences. From the tabs on top, choose Site, and you'll see a list of citation styles in the Style Manager box. You can also tell when that style was updated. Choose the style you want and whether or not you'd like to include URLs of the paper articles in the references. Now, you can either be done and hit OK, or you have two more options. You can check out a style preview, and when the window pops up, you can choose a citation from your list, select Refresh, and here you'll see the in-text citation and the reference page entry. The other thing you can do is select Style Editor, and if for some reason you need to change the formatting of citations, this is where you do it. This isn't usually necessary, though. If you do need to fix a single citation, you can go into that individual entry and make alterations there. When you're all done with your selection, be sure to hit OK so that the change is applied.
