+    The AWS Cloud Development Kit (AWS CDK) is a framework for defining cloud resources in code and provisioning it through AWS CloudFormation.

+    Below is an example of a basic CDK app that deploys a New Relic instrumented Node.js Lambda function:
+    ```ts
+    import * as cdk from 'aws-cdk-lib';
+    import { Construct } from 'constructs';
+    import * as lambda from 'aws-cdk-lib/aws-lambda';
