  Convert this description:
  
  amd is a principal directory that groups 3 subdirectories: _virtual, below and custom_modules.
  In the root directory, '_virtual' is an empty container.
  At the top level, 'below' appears to be unused.
  At the main level, 'custom_modules' stores 1 nested folders: @my-scope.
  Within directory hierarchy 'custom_modules → @my-scope', '@my-scope' is a scoped package with 1 components.
  Within directory hierarchy 'custom_modules / @my-scope / my-base-pkg', Inside 'my-base-pkg', you'll find it sits empty.
