composer create-project codeigniter4/appstarter
then composer update
whenever there is a new release of the framework.app
folder. The affected files can be copied or merged from vendor/codeigniter4/framework/app

is no longer in the root of the project! It has been moved inside the public folder, for better security and separation of components.
