+# Wisp HTTP Client
+
+A modern HTTP client with genuine TLS 1.3 encryption for making secure requests through Wisp servers.
+
+## 🔒 Security Features
+
+**This client provides TRUE end-to-end encryption** using TLS 1.3 with AES-GCM cipher suites. The Wisp server only sees encrypted TLS records, ensuring your HTTP traffic remains private.
+
+✅ **Genuine TLS 1.3 implementation**
+✅ **ECDH key exchange with P-256**
+✅ **AES-128/256-GCM encryption**
+✅ **Certificate validation**
+✅ **SNI (Server Name Indication) support**
+
+## Features
+
+- 🔐 **Real TLS encryption**: True end-to-end security with TLS 1.3
+- 🪶 **Lightweight**: ~25KB vs 552KB for libcurl.js
+- 🌐 **Fetch-compatible API**: Drop-in replacement for `fetch()`
+- ⚡ **High performance**: Multiplexed connections over WebSocket
+- 🎯 **Modern**: Built with TypeScript and WebCrypto APIs
+- 🔧 **Zero dependencies**: No external cryptographic libraries
+
+## What is Wisp?
+
+[Wisp](https://github.com/MercuryWorkshop/wisp-protocol) is a lightweight multiplexing websocket proxy protocol that allows multiple TCP/UDP sockets to share a single websocket connection. This library implements a Wisp client for making HTTP requests through a Wisp server.
+
+## Installation
+
+```bash
+npm install wisp-http-client
+```
+
+## Quick Start
+
+### Using the fetch-like API
+
+```javascript
+import { createFetch } from 'wisp-http-client';
+
+// Create a fetch function that uses a Wisp server
+const fetch = createFetch({
+  wispServerUrl: 'wss://your-wisp-server.com/'
+});
+
+// Use it just like regular fetch
+const response = await fetch('https://api.example.com/data');
+const data = await response.json();
+console.log(data);
+```
+
+### Using the HTTP client directly
+
+```javascript
+import { WispHttpClient } from 'wisp-http-client';
+
+const client = new WispHttpClient({
+  wispServerUrl: 'wss://your-wisp-server.com/',
+  timeout: 30000 // 30 seconds
+});
+
+// Make a GET request
+const response = await client.get('https://api.example.com/users');
+console.log('Status:', response.status);
+console.log('Body:', new TextDecoder().decode(response.body));
+
+// Make a POST request
+const postResponse = await client.post(
+  'https://api.example.com/users',
+  JSON.stringify({ name: 'John', email: 'john@example.com' }),
+  { headers: { 'Content-Type': 'application/json' } }
+);
+
+// Clean up when done
+client.close();
+```
+
+## API Reference
+
+### `createFetch(config)`
+
+Creates a fetch-compatible function that uses Wisp for transport.
+
+**Parameters:**
+- `config.wispServerUrl` (string): URL of the Wisp server
+- `config.timeout` (number, optional): Request timeout in milliseconds (default: 30000)
+
+**Returns:** A function with the same signature as `fetch()`
+
+### `WispHttpClient`
+
+#### Constructor
+
+```javascript
+new WispHttpClient(config)
+```
+
+**Parameters:**
+- `config.wispServerUrl` (string): URL of the Wisp server
+- `config.timeout` (number, optional): Default request timeout in milliseconds
+
+#### Methods
+
+##### `request(url, options)`
+
+Make an HTTP request.
+
+**Parameters:**
+- `url` (string): The URL to request
+- `options` (object, optional):
+  - `method` (string): HTTP method (default: 'GET')
+  - `headers` (object): HTTP headers
+  - `body` (string | Uint8Array): Request body
+  - `timeout` (number): Request timeout in milliseconds
+
+**Returns:** Promise<HttpResponse>
+
+##### `get(url, options)`
+
+Make a GET request.
+
+##### `post(url, body, options)`
+
+Make a POST request.
+
+##### `close()`
+
+Close the connection and clean up resources.
+
+### Types
+
+```typescript
+interface HttpResponse {
+  status: number;
+  statusText: string;
+  headers: Record<string, string>;
+  body: Uint8Array;
+}
+
+interface WispHttpClientConfig {
+  wispServerUrl: string;
+  timeout?: number;
+}
+
+interface RequestOptions {
+  method?: string;
+  headers?: Record<string, string>;
+  body?: string | Uint8Array;
+  timeout?: number;
+}
+```
+
+## Browser Usage
+
+You can use this library directly in the browser:
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+  <title>Wisp HTTP Client Example</title>
+</head>
+<body>
+  <script type="module">
+    import { createFetch } from './node_modules/wisp-http-client/dist/index.esm.js';
+
+    const fetch = createFetch({
+      wispServerUrl: 'wss://your-wisp-server.com/'
+    });
+
+    async function loadData() {
+      try {
+        const response = await fetch('https://api.github.com/users/octocat');
+        const user = await response.json();
+        console.log('User:', user);
+      } catch (error) {
+        console.error('Error:', error);
+      }
+    }
+
+    loadData();
+  </script>
+</body>
+</html>
+```
