I'm heading out the door at the moment, but I wanted to also suggest doing a search on Youtube for a tutorial. It's not hard; you just have to understand what to look for in terms of how tight to go with the top cap so that your headset isn't so tight that it binds or so loose that it has too much play. From there, it's a question of getting tightened correctly. I wish I wasn't in such a rush or I'd try to describe it in detail.
