+# Fasthttp Example
+
+A simple HTTP server example using the `fasthttp` module from `vlib/fasthttp`.
+
+## Features
+
+- Handles GET and POST requests
+- Routes requests to different controllers based on HTTP method and path
+- Returns appropriate HTTP responses with status codes and content
+
+## Building
+
+```sh
+./v examples/fasthttp
+```
+
+## Running
+
+```sh
+./examples/fasthttp/fasthttp
+```
+
+The server will listen on `http://localhost:3000`
+
+## Testing
+
+### Home endpoint
+
+```sh
+curl http://localhost:3000/
+```
+
+### Get user by ID
+
+```sh
+curl http://localhost:3000/user/123
+```
+
+### Create user
+
+```sh
+curl -X POST http://localhost:3000/user
+```
+
+### 404 response
+
+```sh
+curl http://localhost:3000/notfound
+```
+
+## File Structure
+
+- `main.v` - Entry point and request router
+- `controllers.v` - Request handlers for different routes
+- `v.mod` - Module metadata
+
+## Architecture
+
+The example demonstrates:
+
+1. **Request Routing**: The `handle_request()` function routes incoming HTTP requests based on
+   method and path
+2. **Response Handling**: Controllers return HTTP responses with proper headers and status codes
+3. **Content Type**: All responses are returned as `[]u8` (byte arrays)
+
+The fasthttp module handles:
+
+- Low-level socket management
+- Request parsing
+- Connection handling
+- Non-blocking I/O with epoll (Linux) or kqueue (macOS)
