+    # The first argument to `can` is the action you are giving the user
+    # permission to do.
+    # If you pass :manage it will apply to every action. Other common actions
+    # here are :read, :create, :update and :destroy.
+    #
+    # The second argument is the resource the user can perform the action on.
+    # If you pass :all it will apply to every resource. Otherwise pass a Ruby
+    # class of the resource.
+    #
+    # The third argument is an optional hash of conditions to further filter the
+    # objects.
+    # For example, here the user can only update published articles.
+    #
+    #   can :update, Article, published: true
