prompt: Your task is to convert the following English description into an ASCII tree format.
  
  merkletrie is a root directory that maintains 4 subdirectories. Notable ones include filesystem, index, internal among others.
  
  Let me break down the ordering for you:
  
  At the main level, 'filesystem' awaits content.
  At the top level, The 'index' data structure stands empty.
  At the main level, 'internal' encompasses 1 subdirectories: frame.
  At level 2, in directory path 'internal > frame', The 'frame' container has yet to be populated.
  Back to the top level.
  At the main level, Inside 'noder', you'll find it lacks any subdirectories.
  
  
  Format your response in this style:
  ```
  api
   +--plugins
   `--tasks
       `--bundling
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
