 The SDK makes use of both JavaScript and CSS so you need to load two resources in the browser:

 By defining your app key and track identifier as data attributes when including the JavaScript file the SDK auto-configures itself. You can find the app key and track identifier in the [developer console](https://shopgun.com/developers/apps).

 We recommend using environment variables for the config to avoid having secrets in your code base:
 
 ```javascript
 SGN.config.set({
