# Referencing the Canvas SDK

The Canvas SDK is available on [GitHub](https://github.com/forcedotcom/salesforcecanvasframeworksdk), and you have two options for referencing it from your canvas app.

- Host the SDK on your own Web server and access it there
- Access the SDK hosted on the Salesforce server

For example, here’s what the include statement looks like if you host the SDK on your own Web server:

```html
<script type="text/javascript" src="/sdk/js/canvas-all.js"></script>
```

Here’s what the include statement looks like if you reference the hosted SDK:

```html
<script type="text/javascript" src="https://<instance>.salesforce.com/canvas/sdk/js/68.0/canvas-all.js"></script>
```

The ability to reference the SDK on the Salesforce server is useful when you want to include one of the SDK files in a Web app or from a Visualforce page.
