Doug Wikle updated the DataDog/documentation repository by enhancing the AWS integration documentation to support Step Functions in tag-based filtering. He clarified how resource exclusion works and detailed the available AWS metric collection options, ensuring that users can more easily configure and understand these features. Doug used Markdown to structure the documentation and applied disciplined version control practices to link the update to internal tracking. His work focused on clear, user-oriented documentation, reducing potential customer support inquiries by making the new capability explicit. The depth of the update reflects a strong grasp of documentation standards and AWS integration concepts.
