   `--eslint-formatter-bar
  ```
  
  Convert this description:
  
  custom_templates is a origin directory that houses 2 subdirectories: app_template and project_template.
  At the main level, 'app_template' remains unused.
  In the root directory, 'project_template' organizes 2 contained folders: additional_dir, project_name.
  Within directory hierarchy 'project_template / additional_dir', Inside 'additional_dir', you'll find it is empty.
  In nested path 'project_template / project_name', The 'project_name' repository contains nothing at present.
  Back to the top level.
