+
+The easiest way to add ECS to your existing project:
+
+```bash
+# In your project directory
+npx @esengine/cli init
+```
+
+The CLI automatically detects your project type (Cocos Creator 2.x/3.x, LayaAir 3.x, or Node.js) and generates the necessary integration code, including:
+
+- `ECSManager` component/script - Manages ECS lifecycle
+- Example components and systems - Helps you get started quickly
+- Automatic dependency installation

+Using `Laya.Script` component to manage ECS lifecycle is recommended:
 
 ```typescript

-import { Core } from '@esengine/ecs-framework';

-  Laya.timer.frameLoop(1, this, () => {
-    const deltaTime = Laya.timer.delta / 1000;
-    Core.update(deltaTime);  // Auto-updates global services and scene
-  });

+  }

 ```
 
+In Laya IDE, attach the `ECSManager` script to a node in your scene.
