_Finally you can delete all the default generated code linked to the PageController:_

rm test/liveview_chat_web/controllers/page_controller_test.exs
rm lib/liveview_chat_web/controllers/page_controller.ex
rm test/liveview_chat_web/views/page_view_test.exs
rm lib/liveview_chat_web/views/page_view.ex
rm -r lib/liveview_chat_web/templates/page
