Angel Tellez focused on enhancing the documentation for the flex-cluster resource in the mongodb/awscdk-resources-mongodbatlas repository. Over the course of a month, Angel updated the Markdown-based README to clarify usage instructions, explicitly communicate the current upgrade limitations, and guide users toward the recommended CfnCluster resource for managing flex clusters. This documentation work aimed to prevent misconfiguration by making upgrade paths and feature availability transparent. The technical approach centered on clear, concise writing and careful structuring of information, leveraging Markdown and documentation best practices. The depth of the update addressed user confusion and aligned expectations with the resource’s actual capabilities.
