+# Deploy to Render
+
+## Quick Setup
+
+1. **Fork this repository**
+
+2. **Create Render Web Service**:
+   - Go to [Render Dashboard](https://dashboard.render.com)
+   - Click "New" → "Web Service"
+   - Connect your forked repository
+   - Use these settings:
+     - **Build Command**: `npm install && npm run build`
+     - **Start Command**: `node cloud-server-simple.js`
+
+3. **Set Environment Variables** (in Render dashboard):
+   - Go to your service → Environment
+   - Add these variables:
+     ```
+     OPENAI_API_KEY=your-actual-api-key-here
+     OPENAI_BASE_URL=https://api.deepseek.com
+     OPENAI_MODEL=deepseek-chat
+     ```
+
+4. **Deploy** and get your URL: `https://your-app.onrender.com`
+
+5. **Use with Claude Code**:
+   ```bash
+   export ANTHROPIC_BASE_URL=https://your-app.onrender.com
+   export ANTHROPIC_API_KEY=any-string  # Can be any value
+   claude-code
+   ```
+
+## Security Note
+
+⚠️ **Important**: This basic deployment does not include API key authentication between Claude Code and your Render service. Anyone with your Render URL can use your deployed service. For production use, consider:
+
+1. Adding authentication middleware
+2. Using environment-based access control
+3. Implementing rate limiting
+4. Monitoring usage
+
+## Provider Examples
+
+**DeepSeek (Recommended - very cheap):**
+```
+OPENAI_API_KEY=sk-your-deepseek-key
+OPENAI_BASE_URL=https://api.deepseek.com
+OPENAI_MODEL=deepseek-chat
+```
+
+**OpenAI:**
+```
+OPENAI_API_KEY=sk-your-openai-key
+OPENAI_BASE_URL=https://api.openai.com/v1
+OPENAI_MODEL=gpt-4
+```
+
+**OpenRouter:**
+```
+OPENAI_API_KEY=sk-your-openrouter-key
+OPENAI_BASE_URL=https://openrouter.ai/api/v1
+OPENAI_MODEL=anthropic/claude-3.5-sonnet
+```
+
+That's it! Now you can use Claude Code with any provider without running anything locally.
