+# Deploy to Render.com (Free 24/7 Hosting)
+
+## Step 1: Create Render Account
+
+1. Go to **https://render.com**
+2. Sign up with your GitHub account
+
+## Step 2: Push Code to GitHub
+
+```bash
+cd C:\Users\abbasyk\Documents\opencode-hf-space
+git init
+git add -A
+git commit -m "Initial commit"
+git remote add origin https://github.com/YOUR_USERNAME/opencode-bot.git
+git push -u origin main
+```
+
+## Step 3: Create Background Worker on Render
+
+1. Go to **https://dashboard.render.com**
+2. Click **"New +"** → **"Background Worker"**
+3. Connect your GitHub repo
+4. Settings:
+   - **Name**: opencode-telegram-bot
+   - **Runtime**: Node
+   - **Build Command**: `npm install`
+   - **Start Command**: `node bot.js`
+5. Click **"Advanced"** → Add these **Environment Variables**:
+
+| Key | Value |
+|-----|-------|
+| `TELEGRAM_BOT_TOKEN` | `8835963099:AAHvLdFqbpsfDs3hTUBXuFQzSo3LSpedd6k` |
+| `TELEGRAM_CHAT_ID` | `6922119748` |
+| `OPENCODE_ZEN_KEY` | `sk-1IwuYl2EKD0bNtmoEPqBVuWQHlKlc7gN5VLFZnjBrGTUbg7O1376dM9eYg8AHaUv` |
+
+6. Click **"Create Background Worker"**
+
+## Step 4: Verify
+
+- Go to your service page on Render
+- Check **"Logs"** tab - you should see:
+  ```
+  [OK] Starting Telegram bot...
+  [OK] Telegram bot is running!
+  ```
+
+## Free Tier Limitations
+
+- **750 hours/month** (enough for 24/7)
+- **Sleeps after 15 min** of inactivity (but Telegram bot keeps it awake)
+- **Spins up in ~30 seconds** when new message arrives
+
+## Alternative: Fly.io
+
+If Render doesn't work, try Fly.io:
+1. Install: `curl -L https://fly.io/install.sh | sh`
+2. Run: `fly auth login`
+3. Run: `fly launch`
+4. Run: `fly secrets set TELEGRAM_BOT_TOKEN=... TELEGRAM_CHAT_ID=... OPENCODE_ZEN_KEY=...`
+5. Run: `fly deploy`
