# Displaying a Message
1. Let’s try displaying a message in the center of the app. The default center label is set to a black background with white text.
```jsx
// main.js
App.showCenterLabel("Hello world");
```
2\. Result
{% hint style="warning" %}
Please Note
* For the tutorial, we recommend setting the app type to Mini-Game.
* The JSON file name must be “main”. Please create a new text file and name it main.js.
* If you do not know how to deploy an app, please refer to the [**ZEP Script Deployment Guide**](/zep-script/zep-script-guide/zep-script-development-guide/zep-script-deployment-guide.md).
