+
+## Features

+- 🚀 **Fast & Scalable**: Built on Cloudflare Workers for global edge deployment
+- 🔗 **Custom Short Paths**: Create custom short links or use auto-generated ones
+- 🔐 **Secure API**: Token-based authentication for API access
+- 📊 **Link Management**: List and retrieve information about existing short links
+- 🌐 **Global CDN**: Leverages Cloudflare's global network for fast redirects
+
+## Quick Start
+
+### Prerequisites
+
+- Node.js (v16 or later)
+- npm or yarn
+- Cloudflare account
+- Wrangler CLI

+cd shortlink
+```
+
+2. Install dependencies:
+```bash
+npm install
+```
+
+3. Configure your environment (see [Configuration](#configuration) section)
+
+4. Start development server:
+```bash
+npm run dev
+```
+
+5. Deploy to Cloudflare Workers:
+```bash
+npm run deploy
+```
+
+## Configuration
+
+### Environment Variables
+
+You need to configure the following in your Cloudflare Workers dashboard:
+
+#### KV Namespace
+1. Go to **Workers & Pages** > **KV**
+2. Create a new namespace called `SHORT_LINK`
+3. In your worker settings, bind it under **Settings** > **Variables** > **KV Namespace Bindings**:

+   - KV namespace: Select your created namespace
+
+#### Environment Variables
+In **Settings** > **Variables**, add:
+- `TOKEN`: Your API authentication token (choose a secure random string)
+
+### Local Development
+
+For local development, create a `wrangler.toml` file (if not already configured) with your KV namespace bindings.
+

+{
+  "url": "https://example.com/very-long-url",
+  "path": "custom-path"  // Optional: custom short path
+}
+```
+
+**Response:**
+```json
+{
+  "original": "https://example.com/very-long-url",
+  "url": "https://your-domain.com/abc123"
+}
+```
+
+### Get Link Information
+
+**GET** `/api/link/{path}`
+
+Retrieve information about a specific short link.
+
+**Response:**
+```json
+{
+  "exists": true,
+  "path": "abc123",

+      "expiration": null,
+      "metadata": null
+    }
+  ],
+  "list_complete": true,
+  "cursor": null
+}
+```
+
+## Usage Examples
+
+### Using cURL
+
+Create a short link:
+```bash
+curl -X POST https://your-domain.com/api/shorten \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"url": "https://example.com/long-url"}'
+```
+
+Create a custom short link:
+```bash
+curl -X POST https://your-domain.com/api/shorten \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"url": "https://example.com/long-url", "path": "my-link"}'
+```
+
+### Using the Short Link
+
+Once created, visit the short link in your browser:
+```
+https://your-domain.com/abc123
+```
+
+This will redirect you to the original URL with a 301 permanent redirect.
