A Window object is created and stored in the stash by
-L<Reaction::UI::RootController>, it is used to contain all the
+L<Reaction::UI::Controller::Root>, it is used to contain all the
elements (ViewPorts) that make up the UI. The Window is rendered in
-the end action of the RootController to make up the page.
-
-To add L<ViewPorts|Reaction::UI::ViewPort> to the stack, read the
-L<Reaction::UI::FocusStack> and L<Reaction::UI::ViewPort> documentation.
-
-Several Window attributes are set by
-L<Reaction::UI::RootController/begin> when a new Window is created,
-these are as follows:
-

+To add L<ViewPorts|Reaction::UI::ViewPort> to the stack, use the
+L<Reaction::UI::Controller/push_viewport> method. For more detailed

+L<Reaction::UI::ViewPort> documentation.
