"a complete guide"

and then in the first step u already using .rbenv without really mention it before (i also read ur other article where u saying that u using it)

maybe you can add a link to a good rbenv install faq or something like that. makes it easier for some people who might hit ur guide without rbenv.

but all in all a very good read. i will give it a try on the weekend in one of my apps.
