 ## Overview
 
+This tool has been created to be used initially by this repo (aws/aws-cdk). Long term the goal is
+for this tool to be a general tool that can be used for running CDK integration tests. We are
+publishing this tool so that it can be used by the community and we would love to receive feedback
+on use cases that the tool should support, or issues that prevent the tool from being used in your
+library.
+
+This tool is meant to be used with the [integ-tests](https://github.com/aws/aws-cdk/tree/master/packages/%40aws-cdk/integ-tests) library.
