+Running Instructions:
+- To run this FastAPI application, make sure you have FastAPI and Uvicorn installed.
+- Save this script as 'fastapi_incr.py'.
+- Run the application using the command: `uvicorn fastapi_incr:app --reload --port PORT_NUMBER`
+- The server will start on `http://localhost:PORT_NUMBER`. Use this base URL to make API requests.
+- Go to `http://localhost:PORT_NUMBER/docs` for API documentation.
