+## Dual Database Setup
+
+This project supports using both a local MongoDB instance and MongoDB Atlas for database operations. This flexibility allows for easy switching between a local database for development and a cloud-based database for production or testing purposes.
+
+To switch between the local MongoDB and MongoDB Atlas, instantiate the `Database` class with the `use_atlas` parameter set accordingly:
+- For local MongoDB, use `Database(use_atlas=False)`.
+- For MongoDB Atlas, use `Database(use_atlas=True)`.
+
+Note: The `recognise_face()` API endpoint is configured to exclusively use MongoDB Atlas due to its reliance on cloud-specific features.
