  Convert this description:
  
  ignore is a master directory that comprises 2 subdirectories: __snapshots__ and semi.
  At the main level, Inside '__snapshots__', you'll find it remains unused.
  At the top level, 'semi' maintains 1 subdirectories: __snapshots__.
  In nested path 'semi → __snapshots__', '__snapshots__' is barren.
