+# CDK IoT Sample Project
+
+This is a sample project which shows how to create, deploy and start a simple Node.js IoT application. 
+The code in this sample project was written by using the AI companionship of Amazon CodeWhisperer. 
+The comments in the code show what Amazon CodeWhisperer was 'told' to generate. 
+
+The project is composed of two parts:
+
+1. The Typescript CDK infrastructure as code, which creates the needed resources as follows:
+   - An IoT policy, 
+   - An IoT Rule, 
+   - An AWS Lambda function which is invoked as a Rule Action.
+The `cdk.json` file tells the CDK Toolkit how to execute your app.
+
+2. A Javascript application, which:
+   - Creates an AWS IoT Thing,
+   - Creates the needed IoT thing identity (certificate and keys),
+   - Attaches the policy to the certificate, and the certificate to the thing,
+   - Creates an MQTT client using the MQTT.JS open source library,
+   - Starts the MQTT client, connects to AWS IoT Core, 
+   - Subscribes and publishes data on interval on an MQTT topic.
+
+## Pre-Requisites
+* To be able to deploy the CDK resources, as well as run your application, you need to:
+  * Ensure you provide the scripts the needed AWS credentials.
+  * Replace the `ENDPOINT`value with your AWS Account and REGION IoT Endpoint in line 11 in [here](test-app/app.js).
+
+## Useful commands
+
+* To prepare and deploy the AWS resources created using CDK:
+
+  * `npm install`     install dependencies as node modules
+  * `npm run build`   compile typescript to js
+  * `npm run watch`   watch for changes and compile
+  * `npm run test`    perform the jest unit tests
+  * `cdk deploy`      deploy this stack to your default AWS account/region
+  * `cdk diff`        compare deployed stack with current state
+  * `cdk synth`       emits the synthesized CloudFormation template
+
+* To run the Javascript application:
+  * `npm install`     install dependencies as node modules
+  * `node test-app/app.js`   run JavaScript app
+
+## Clean-up steps
+* Clean up your app-created resources, certificates, thing etc.
+   * `node test-app/clean-up-app.js`   run JavaScript app
+
+* Clean up your CDK created resources:
+  * `cdk destroy`     delete resources from your AWS Account
