## **Introduction**
-**MicroPie** is a fast, lightweight, modern Python web framework that supports asynchronous web applications with built-in HTTP and WebSocket handling. Designed with **flexibility** and **simplicity** in mind, MicroPie enables you to handle high-concurrency applications with ease, supporting both traditional HTTP requests and real-time bidirectional communication via WebSockets.

You can see how to handle POST JSON data at [examples/api](https://github.com/patx/micropie/tree/main/examples/api).
-### **3. Native WebSocket Support**
-MicroPie includes built-in WebSocket support for real-time, bidirectional communication. Define WebSocket handlers using methods prefixed with `ws_` (e.g., `ws_chat`). The `WebSocket` class provides methods to accept connections, send/receive text or JSON, and close connections.
+### **3. Real-Time Communication with Socket.IO**
+Because of its designed simplicity, MicroPie does not handle WebSockets out of the box. While the underlying ASGI interface can theoretically handle WebSocket connections, MicroPie’s routing and request-handling logic is designed primarily for HTTP. While MicroPie does not natively support WebSockets, you can easily integrate dedicated Websockets libraries like **Socket.IO** alongside Uvicorn to handle real-time, bidirectional communication. Check out [examples/socketio](https://github.com/patx/micropie/tree/main/examples/socketio) to see this in action.

- await websocket.close()
-```

-- Connect to the WebSocket endpoint at [ws://127.0.0.1:8000/chat](ws://127.0.0.1:8000/chat).
