You could have at least mentioned the title of the section however, this way one doesn't need to guess where exactly you found it...
Wearing my technical writer's hat: I agree in principle, but the problem is that section header text (not to mention URLs derived from it) can be very easily broken.
On the "teach a man to fish" principle, in this context I think it's more useful to highlight the documentation root- which a lot of people overlook in favour of the wiki- plus some brief hints on how to use it.
