During January 2025, Diogo Ferrao enhanced the authentication documentation for the stackitcloud/stackit-sdk-go repository, focusing on improving developer onboarding and setup clarity. He restructured the README to clearly distinguish between key flow and token flow, providing detailed, actionable configuration steps for each method. This work leveraged his skills in technical writing and documentation, as well as his familiarity with Go and Markdown. By addressing common setup questions and clarifying authentication workflows, Diogo reduced onboarding time and friction for SDK users. The depth of the update reflects a thoughtful approach to usability, though the work was limited to documentation rather than code changes.
