# Installation

> Install @kontextso/sdk-js via npm or load it from CDN.

<Note>
  You'll need a [publisher account](/publishers#getting-started-is-easy) to obtain your `publisherToken` and placement codes.
</Note>

## npm

```bash theme={null}
npm install @kontextso/sdk-js@4
```

## CDN

Or load the SDK from our CDN as a global script:

```html theme={null}
<script src="https://server.megabrain.co/sdk/js?type=global&publisherToken={publisherToken}"></script>
```

When loaded via CDN the API is available on `window.KontextSdk`. Replace `{publisherToken}` with your actual token.
