+AUTO-DEPLOY SETUP - Fix Database Disconnection After Git Pull
+===============================================================================
+
+PROBLEM YOU'RE EXPERIENCING:
+- Git auto-pulls new code to production
+- Database stops connecting
+- You have to manually run deploy.sh to fix it
+
+SOLUTION:
+Automatic service restart after every git pull!
+
+===============================================================================
+INSTALLATION (Run Once on Production Server)
+===============================================================================
+
+SSH into your production server and navigate to Connect-5 directory, then run:
+
+bash setup-auto-deploy.sh
+
+That's it! The script will:
+✅ Install a git post-merge hook
+✅ Detect your service manager (PM2/systemd/manual)
+✅ Configure automatic restart after git pull
+
+===============================================================================
+HOW IT WORKS
+===============================================================================
+
+After installation, every time git pulls new code:
+
+1. Git auto-pull happens (your existing automation)
+2. Git triggers the post-merge hook automatically
+3. Hook checks if package.json changed → runs npm install if needed
+4. Hook restarts the Node.js service automatically
+5. Database reconnects immediately
+6. No manual intervention needed!
+
+===============================================================================
+WHAT'S INCLUDED
+===============================================================================
+
+📁 git-hooks/post-merge
+   - The hook script that runs after git pull
+   - Handles: npm install + service restart
+   - Works with: PM2, systemd, or manual process restart
+
+📜 setup-auto-deploy.sh
+   - One-time setup script
+   - Copies hook to .git/hooks/
+   - Makes it executable
+   - Tests which service manager you're using
+
+===============================================================================
+QUICK SETUP (Copy/Paste This)
+===============================================================================
+
+On your production server:
+
+cd /path/to/Connect-5
+bash setup-auto-deploy.sh
+
+Answer "y" when asked to test the hook.
+
+===============================================================================
+VERIFICATION
+===============================================================================
+
+After setup, test it:
+
+1. Make a small change to README.md on your local machine
+2. Git push from local
+3. Wait for server to auto-pull (your existing setup)
+4. SSH into server and check:
+   
+   # Check if service restarted
+   pm2 logs connect5
+   # OR
+   sudo systemctl status connect5
+   # OR
+   tail -f server.log
+
+5. You should see:
+   "🔄 Git Pull Detected - Running Auto-Deploy"
+   "✅ Auto-Deploy Complete!"
+
+===============================================================================
+NO MORE MANUAL DEPLOYS!
+===============================================================================
+
+Before: Git pulls → Database disconnects → You run deploy.sh manually
+After:  Git pulls → Hook runs → Service restarts → Database reconnects ✅
+
+You'll never need to run deploy.sh manually again for database connection issues!
+
+===============================================================================
+ROLLBACK (If Needed)
+===============================================================================
+
+To disable auto-deploy:
+
+rm .git/hooks/post-merge
+
+To re-enable:
+
+bash setup-auto-deploy.sh
