Arnaud Bersier contributed to the heig-vd-dai-course repository by updating project documentation to accurately reflect team membership. During September 2025, Arnaud focused on maintaining the README file, specifically adding a new contributor to ensure transparency and proper recognition within the team. This work involved editing Markdown files and verifying that the documentation aligned with onboarding and governance standards, supporting project clarity without introducing code changes. The technical approach centered on clear, standards-compliant documentation practices, leveraging skills in Markdown and documentation management. While the scope was limited to a single feature, the update maintained project integrity and supported effective team collaboration.
