I agree even if you make the dialog (NPC, ect.) explain it in detail most people will just click past it not reading or realizing whats said. I would suggest its put somewhere in a NPC, FAQ, ect, reachable within game that people can easily point them in the direction of. This way if you want to be helpful it's not as annoying and you will hear less "How many steps does it take to hatch an egg." in Global chat.
