Worked on enhancing the documentation for the flex-cluster resource in the mongodb/awscdk-resources-mongodbatlas repository, focusing on improving clarity around usage instructions and upgrade status. Updated the README using Markdown to provide explicit guidance for users, including directing them to the CfnCluster resource for managing flex clusters and noting the current unavailability of upgrades to prevent misconfiguration. The documentation changes aimed to align user expectations with the resource’s actual capabilities and recommended upgrade paths. This work emphasized clear technical communication and careful documentation practices, ensuring that users have accurate, actionable information when deploying or managing flex-cluster resources.
