+This sample is for reference on connecting using a Custom Authorizer.
+Using a Custom Authorizer allows you to perform your own authorization using an AWS Lambda function.
+See Custom Authorizer for more information.
+You will need to setup your Custom Authorizer so that the lambda function returns a policy document.

 If you want to use simple or custom auth (or static creds, or basic auth, etc) instead,
 then you will need to replace part of the sample (connection\_setup function) with a code snippet we provided in its corresponding readme.
