Joaquin Romo enhanced the documentation for the MongoDB Atlas FlexCluster CloudFormation resource in the mongodb/mongodbatlas-cloudformation-resources repository, focusing on improving clarity for developers managing cloud resources. He updated the Markdown-based documentation to clarify the resource’s intended use, outlined upgrade considerations, and directed users toward the recommended MongoDB::Atlas::Cluster resource for ongoing management. Joaquin also created a new example README to guide onboarding and reduce ambiguity for users creating FlexClusters. His work emphasized best practices in documentation, leveraging his skills in technical writing and resource management to streamline developer experience and reduce support overhead, though it was limited in scope and duration.
