During September 2025, this developer focused on enhancing documentation for the heig-vd-dai-course/heig-vd-dai-course repository by updating the CONTRIBUTORS section in the README.md file to include a new contributor. The work centered on improving transparency and recognition for project participants, which supports better onboarding and contributor management. Using Markdown for documentation and Git for version control, the developer ensured that changes were traceable and aligned with issue tracking through detailed commit messages. The update was isolated to documentation, introducing no changes to build or runtime behavior, thereby maintaining project stability while reinforcing best practices in collaborative open-source workflows.
