echo "🔄 How the Docker-Based Update System Works:"
echo "=========================================="
echo "The Update Settings in the frontend (Settings page, bottom section) now uses Docker:"
echo ""
echo "1. **Check for Updates Button**:"
echo "   - Calls GET /api/updates/check"
echo "   - No longer requires OAuth authentication!"
echo "   - Checks Docker registry for new image versions"
echo "   - Shows current vs latest version"
echo ""
echo "2. **Install Update Button**:"
echo "   - Appears when updates are available"
echo "   - Calls POST /api/updates/install"
echo "   - Uses docker compose to pull and restart services"
echo "   - Automatic health checks after update"
echo ""
echo "3. **Docker Images Used**:"
echo "   - Backend: ghcr.io/dvorinka/trackeep/backend:main-aef1e39"
echo "   - Frontend: ghcr.io/dvorinka/trackeep/frontend:main-aef1e39"
echo ""
echo "4. **Auto-Update Settings**:"
echo "   - UI still exists (localStorage)"
echo "   - For true auto-updates, use the Docker scripts"
echo ""
echo "� To Test the Full Update Flow:"
echo "1. Go to Settings > Update Settings (bottom of left nav)"
echo "2. Click 'Check Now' - should work without login"
echo "3. If update available, click 'Install Update'"
echo "4. System will pull new images and restart services"
echo ""
echo "� For Automated Daily Updates:"
echo "1. Use: sudo ./scripts/setup-auto-update.sh"
echo "2. Or: sudo ./scripts/setup-systemd-update.sh"
echo "3. These pull your specific tagged images daily"
echo ""
echo "✨ Key Improvements:"
echo "- ❌ No OAuth authentication required"
echo "- ✅ Uses Docker pulls (safer, atomic updates)"
echo "- ✅ Works with your specific image tags"
echo "- ✅ Faster and more reliable than file-based updates"
echo "- ✅ Better rollback capabilities"
