Which docking tutorial, the one in the simulation, or the one in the main quest?
Oh wait. I may have missed the simulation? Now that you mention it, I recall some talk about a simulation, but I can't remember when or where.
This was after starting the first campaign quest; I was flying up to one of the warp rings, and there was a large text box talking about docking with the F3 button, but it also mentioned some other stuff that I didn't fully read (I think it was about alternate ways to dock). I figured it out after a minute though.
