Major improvements to upgrade process and systemd integration:

✅ Smart Service Management
- Automatic detection of running service before upgrades
- Graceful service stop/start during upgrade process
- State preservation - maintains service running state
- Enhanced logging and user feedback throughout upgrades

✅ Enhanced Configuration Protection
- Never overwrite user-modified config.yaml files
- Priority-based configuration preservation system
- Automatic backup creation before any changes
- Clear user notifications about configuration protection

✅ Improved Systemd Integration
- Fixed systemd service file configuration issues
- Resolved GROUP permission errors
- Simplified security settings for reliability
- Better error handling and service startup

✅ Updated Documentation
- Comprehensive README updates with new features

+### ✨ Smart Service Management
+
+The installer provides intelligent service handling during upgrades:
+
+- **Automatic Detection**: Detects if the service is running before upgrades
+- **Graceful Shutdown**: Safely stops the service before applying updates
+- **Auto-Restart**: Restarts the service after successful upgrades
+- **State Preservation**: Maintains the service's previous running state
 
 ### Basic Service Management

-# Enable the service (starts on boot)
+# Enable the service (starts on user login)
 systemctl --user enable cliproxyapi.service
 
 # Start the service

 # Stop the service
 systemctl --user stop cliproxyapi.service
+
+# Restart the service
+systemctl --user restart cliproxyapi.service
+```
+
+### Service Status During Upgrades
+
+When you run `./cliproxyapi-installer upgrade`, the installer will:
+
+1. **Check** if the service is currently running
+2. **Stop** the service gracefully if it's active
+3. **Apply** the upgrade (download, extract, update files)
+4. **Restart** the service if it was running before
+5. **Report** the final service status
+
+You'll see output like:
+```
+[INFO] Service is currently running and will be restarted after upgrade
+[INFO] Stopping CLIProxyAPI service...
+[SUCCESS] Service stopped
+...
+[INFO] Restarting CLIProxyAPI service...
+[SUCCESS] Service restarted successfully
