Thibault Matthey focused on improving documentation hygiene in the heig-vd-dai-course repository by updating the README to recognize contributors more transparently. He delivered a non-functional change that added his name to the Contributors section, using Markdown to ensure clarity and consistency in project records. This update did not introduce new features or bug fixes but enhanced the project’s traceability and onboarding experience for future collaborators. Thibault’s work centered on documentation best practices, emphasizing the importance of accurate contributor history. The technical approach relied on careful editing and version control, demonstrating attention to detail in maintaining collaborative project documentation standards.
