How do you post stories not entries on livejournal?

I've been trying to understand this for awhile. You know how sometimes you look at an entry on LJ and it's a story and it has the sections on it saying pairing and summary and beta, and all of that, well, I don't know how to get all of that. It just says entry when I look for it, and I think if I had all the other stuff, it would help people look at my stories instead of just passing them by, if you know what you mean. Can someone help?
