+Before getting started, you need to create a persistent storage layer where the idempotency utility can store its state - your lambda functions will need read and write access to it.
 
 As of now, Amazon DynamoDB is the only supported persistent storage layer, so you'll need to create a table first.
 
-> Example using AWS Serverless Application Model (SAM)
+**Default table configuration**
