During September 2025, Santiago Sugrañes focused on improving documentation quality for the heig-vd-dai-course/heig-vd-dai-course repository. He delivered a comprehensive cleanup of course materials, updating the student roster and refactoring both README.md and PRESENTATION.md files to enhance clarity and consistency. Santiago addressed HTML escaping issues within documentation, ensuring correct rendering and maintainability. His work emphasized documentation hygiene and the application of Markdown best practices, while also standardizing class IDs and student names across modules. Although the scope was limited to documentation, the changes contributed to a more accessible onboarding experience and improved the overall structure of the project’s written materials.
