  At the main level, Inside 'custom', you'll find it has been left empty.
  In the root directory, Within 'src', you'll find 1 child directories for code structure.
  At level 2, in directory path 'src > readme', Inside 'readme', you'll find it contains no subdirectories.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
