Worked on the heig-vd-dai-course repository to enhance documentation accuracy by updating the Class A roster in the project’s README file. Focused on ensuring that enrollment data remained current, the developer used Markdown to clearly present roster information and leveraged Git-based version control for transparent change tracking. This update improved onboarding processes and made instructor and student visibility more reliable, reducing the need for manual roster inquiries. The work demonstrated attention to lightweight change management and maintainability, with a single feature delivered during the period and no bugs reported. The contribution centered on documentation practices rather than application code or bug fixes.
