```jsx
// main.js

App.showCenterLabel("Hello world");
```

<div align="left"><figure><img src="/files/hoELhaJFwaN3saDD6MXa" alt=""><figcaption></figcaption></figure></div>

Please Note&#x20;

* For the tutorial, we recommend setting the app type to Mini-Game.&#x20;
* The JSON file name must be “main”. Please create a new text file and name it main.js.&#x20;
* If you do not know how to deploy an app, please refer to the [<mark style="color:purple;">**ZEP Script Deployment Guide**</mark>](/zep-script/zep-script-guide/zep-script-development-guide/zep-script-deployment-guide.md)<mark style="color:purple;">.</mark>
