 ### Where should I start?
 
 If you are just getting started make sure you [install this sdk](https://github.com/aws/aws-iot-device-sdk-js-v2#installation) and then build and run the [basic PubSub](https://github.com/aws/aws-iot-device-sdk-js-v2/tree/main/samples#pubsub)

 The aws-iot-device-sdk-v2 library consists of two parts, [node(native)](https://aws.github.io/aws-iot-device-sdk-js-v2/node/index.html) and [browser](https://aws.github.io/aws-iot-device-sdk-js-v2/browser/index.html). The library will access the **native** API by default. You can configure the path in the `tsconfig.json` file to ensure that the app utilizes the **browser** API.
