Nobody likes to read a mountain of text. After tons of playtests I've seen that about half of the players never bother to read tutorials. Lots of people prefer to jump in and figure things out for themselves. When making instructions, I try to minimize the amount text and provide pictures that can better explain the details. People like discovering strategies on their own, so I just give the basics on how to get started. One sentence is pretty easy on the eyes don't you think?
