During September 2025, Pierre Gellet contributed to the heig-vd-dai-course/heig-vd-dai-course repository by updating the CONTRIBUTORS section in the README.md file to include his name. He focused on documentation accuracy and contributor recognition, ensuring that project records remained transparent and up to date. Pierre used Markdown for documentation and leveraged Git for version control, demonstrating disciplined commit practices and clear traceability by referencing related issues in commit messages. While the work did not involve code changes or bug fixes, it improved onboarding for new contributors and maintained project stability, reflecting a careful approach to documentation and collaborative project management.
