# Getting Started

The library has been configured to work in multiple environments:

* UMD (Browser)
* ESM (Client-side applications)

### UMD (Browser)

```markup
<script src="https://unpkg.com/@xapi/cmi5"><script>

<script type="text/javascript">
  // Create Cmi5 instance
  const cmi5 = new Cmi5();

  // Initialize AU
  cmi5.initialize();
<script>
```

### ES module (Client-side applications)

For client-side applications built using imports, an ES Module is available for you to install and `import`  into your project.

```bash
npm i @xapi/cmi5 --save
```

```typescript
import Cmi5 from "@xapi/cmi5";

// Create Cmi5 instance
const cmi5: Cmi5 = new Cmi5();

// Initialize AU
cmi5.initialize();
```
