+### Keploy API Test Generator for FastAPI with MongoDB
+
+This project demonstrates how to use Keploy to automatically generate API tests for a FastAPI application that interacts with a MongoDB database. Keploy captures the API requests and responses, allowing you to create comprehensive test cases effortlessly.
+
+Keploy API Test Generator: https://keploy.io/docs/running-keploy/api-test-generator/
+
+### About the Project
+
+This is FastAPI + MongoDB backend written for a Quiz Application. The application allows users to perform CRUD operations on quiz data stored in a MongoDB database.
