  Convert this description:
  
  app is a base directory that maintains 2 subdirectories: pages and public.
  At the top level, 'pages' maintains 1 subdirectories: api.
  In nested path 'pages > api', 'api' keeps 1 subdirectories: stateful.
  At level 3, in directory path 'pages / api / stateful', Inside 'stateful', you'll find it remains unused.
  At the main level, Inside 'public', you'll find it is devoid of content.
