  Be sure to have a copy of the Bootstrap stylesheet available on your
  application, you can get it on http://twitter.github.com/bootstrap.

  Inside your views, use the 'simple_form_for' with one of the Bootstrap form
  classes, '.form-horizontal', '.form-inline', '.form-search' or
  '.form-vertical', as the following:

    = simple_form_for(@user, :html => {:class => 'form-horizontal' }) do |form|
