Foundation 3.0.5 installing issue with rails 3.2.6

Question

I just started a new project and added zurb-foundation to the Gemfile.
Bundle install show a sass compatibility problem so i run bundle update and bundle install and everything seems ok.

But when I do rails g foundation:install as said in the documentation (https://github.com/zurb/foundation-rails) it's telling me : Could not find generator foundation:install.
Yet I did bundle install so I don't understand.

Thanks for any help !
Here is my Gemfile :

gem 'rails', '3.2.6'
gem 'sqlite3'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  gem 'uglifier', '>= 1.0.3'
  gem 'zurb-foundation', '~> 3.0.5'
end

gem 'jquery-rails'

And the result of bundle install :

Answer 1

Managed to do it with foundation.zurb.com/docs/gem-install.php#simple2.
Github documentation is not up to date.

Answer 2

Since the links above are no longer correct, for Foundation 3.0, use

compass create <project-name> -r zurb-foundation --using foundation

(can be found on the Foundation Documentation: Compass page)
