-### 🚀 PM2 Multi-Process Deployment
-
-Use PM2 for production environment multi-process deployment, providing better performance and stability.
-
-**Important Note**: In PM2 cluster mode, all processes share the same port, and PM2 automatically performs load balancing.
-
 ### 🤖 Smart Start Mode
 
-Using `npm start` can automatically determine the startup method:
-
-- When `PM2_INSTANCES=1`, uses single-process mode
-- When `PM2_INSTANCES>1`, uses Node.js cluster mode
-- Automatically limits process count to no more than CPU cores
+Using `pnpm start` starts the server directly with Node.js:
