+== Authorizing Controller Actions
+
+As mentioned in the Getting Started section, you can use the +load_and_authorize_resource+ method in your controller to load the resource into an instance variable and authorize it. If you have a nested resource you can specify that as well.
+
+  load_and_authorize_resource :nested => :author
+
+You can also pass an array to the :+nested+ attribute for deep nesting.
+
+If you want to customize the loading behavior on certain actions, you can do so in a before filter.

+    before_filter :find_book_by_permalink, :only => :show
+    load_and_authorize_resource

+      @book = Book.find_by_permalink!(params[:id)
+    end
+  end
+
+Here the @book instance variable is already set so it will not be loaded again for that action. This works for nested resources as well.
