• Researched and decided to use django-mptt for comments. This helps us with managing hierarchical data. Here's the documentation. There are useful tags for managing data with django template tags (indentation etc.), but if it is not compatible with react we can always manually use the fields.
• Updated Comment model accordingly.
• Created 2 API endpoints with 5 APIs in total.
• Documented in detail with Swagger. Here's a preview.
  
• Tested with both Postman and Swagger.
