# Quick start

> Set up the Duix H5 SDK and start your first real-time digital human session in under one minute.

## Installation

Install the Duix H5 SDK via **npm**:

```bash theme={null}
npm install duix-guiji-light --save
```

## Import and Initialize

Import the SDK and create a new instance.
The init() method sets up the rendering container, authentication, and platform connection.

```js theme={null}
import Duix from 'duix-guiji-light';

// Create Duix instance
const duix = new Duix();

// Initialize SDK
duix.init({
  sign: 'xxxx',                        // Authentication signature
  containerLable: '.remote-container', // DOM container selector
  conversationId: '',                  // Session ID
  platform: 'duix.com'                 // Platform domain
});
```

## Start the Session

Once initialization succeeds, listen for the initialSuccess event before calling start().
This ensures all required assets and network resources are ready.

```js theme={null}
duix.on('initialSuccess', () => {
  // Start session after successful initialization
  duix.start({
    openAsr: true                      // Enable real-time ASR immediately
  }).then(res => {
    console.info('Session started:', res);
  }).catch(err => {
    console.error('Session start failed:', err);
  });
});


```

**Note:** Do not store the duix instance inside a reactive data object (e.g., Vue’s data() or React’s state). SDK instances should remain stable references outside reactivity systems.
