prompt: Your task is to convert the following English description into an ASCII tree format.
  
  core is a main directory that groups 6 subdirectories. Notable ones include components, global-api, instance among others.
  
  The project source code seems to be organized in the 'components' folder.
  
  Let me break down the design for you:
  
  At the main level, The 'components' collection is vacant.
  At the top level, Inside 'global-api', you'll find it is barren.
  At the main level, 'instance' carries 1 folders: render-helpers.
  In nested path 'instance / render-helpers', Inside 'render-helpers', you'll find it remains unused.
  Back to the top level.
  At the main level, The 'observer' collection contains nothing at present.
  In the root directory, Inside 'util', you'll find it stands empty.
  In the root directory, 'vdom' includes 2 subdirectories: helpers, modules.
  Within directory hierarchy 'vdom → helpers', Inside 'helpers', you'll find it has no folders inside.
  In nested path 'vdom / modules', The 'modules' folder hasn't been filled with any content.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  vcs
   +--git
   |   `--internal
   `--internal
       +--resolver
       +--services
       `--spec
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
