# Customize Well-Architected Reviews for DynamoDB

The AWS Well-Archtected Tool makes it easy to create custom lenses by providing a json template that you can use. The template outlines how the lens content must be defined, and it controls how the lens is presented within the AWS Well-Architected Tool. This repo contains the recommended DynamoDB custom lens json file which can be used to create a DynamoDB Custom Lens in Well-Architected console from json template with the following steps:
1. [Prepare your custom lens Well-Architected template json file](#prepare-your-custom-lens-well-architected-template-json-file)
2. [Navigate to the AWS Well-Architected Tool on the AWS console and create custom lens](#navigate-to-the-aws-well-architected-tool-on-the-aws-console-and-create-custom-lens)
3. [Publish your custom lens and attach a version tag](#publish-your-custom-lens-and-attach-a-version-tag)
4. [Review workloads using custom lenses](#review-workloads-using-custom-lenses)
