 AWS Data Wrangler layers are also available in the `AWS Serverless Application Repository <https://serverlessrepo.aws.amazon.com/applications>`_ (SAR).
 
-Here is an example of how to create the Lambda layer in your CDK app:
+The app deploys the Lambda layer version in your own AWS account and region via a CloudFormation stack.
+This option provides the ability to use semantic versions (i.e. library version) instead of Lambda layer versions.
