What the client really needs is an in-game tutorial that shows you not only the rules of the game, but where to go in-client to find a lot of the information that isn't in obvious places (ideally the client would have everything in obvious places but maybe that isn't possible?). Rulebook links may be a decent reference but honestly I don't think links to rulebooks solve the problem here.
Unfortunately, a tutorial has been on the to-do list since the client launched a few years ago and there have been no whispers at all of any progress on that front. A while ago I did the next best thing and offered a quick video to the devs which shows where things are in the client, but unfortunately the devs didn't even bother to reply to that submission.
So as good of an idea it is to improve the new player experience, and as desperately as the client needs something like a tutorial to help new players, it looks like they are just not interested in improving the client in the one single way that would do the most. Sorry :-(
