-Adapter for [elysia](https://github.com/elysiajs/elysia) to use Elysia in Nodejs environment.
+
+A high-performance, fully-featured adapter for [Elysia](https://github.com/elysiajs/elysia) to run on the Node.js environment using `uWebSockets.js`.
+
+This adapter brings the raw performance of `uWebSockets.js` to Node.js, providing a server environment that is architecturally consistent with Elysia's native Bun runtime.
+
+## Features
+
+-   🚀 High-performance HTTP server
+-   🔌 **Full WebSocket Support**: Includes the powerful `publish/subscribe` API.
+-   streamed bodies: generator support
+-   🦊 Near 1:1 API compatibility with the Bun adapter.
 
 ## Installation
+
 ```bash
 bun add @elysiajs/node
 ```
 
 ## Example
+
 ```typescript
 import { Elysia } from 'elysia'
 import { node } from '@elysiajs/node'
 
 const app = new Elysia({ adapter: node() })
-    .get('/', () => 'Hello Node!')
-    .listen(3000)
+	.get('/', () => 'Hello Node!')
+	.listen(3000)
 ```

-### Note
-Node adapter is not feature complete yet. Some features are not supported, such as:
-- not support `ws` method
