Colin Stefani updated the heig-vd-dai-course repository to improve the accuracy of class enrollment records by adding Colin Stefani to the Class A roster in the project’s README.md. This work focused on documentation, leveraging Markdown for clear formatting and Git-based version control to ensure traceable, maintainable changes. The update addressed onboarding clarity and reduced confusion for both instructors and students by aligning the documentation with current enrollment data. While the scope was limited to a single feature and did not involve bug fixes or complex logic, the work demonstrated careful attention to documentation standards and lightweight change management practices.
