+== Rails 3 version
+
+Garlic doesn't work with Rails 3, so here's how to test resources_controller in the meantime.
+
+Generate a rails app:
+
+  rails new rc_test
+
+and then add the following to the generated Gemfile:
+
+  gem 'rspec', '~> 2.0.0.beta.20'
+  gem 'rspec-rails', '~> 2.0.0.beta.20'
+
+Then run
+
+  bundle install
+  rails generate rspec:install
+
+Copy resources_controller into vendor/plugins and run
+
+  rake rcov:verify && rake spec:generate
+
+from the resources_controller directory
