During July 2025, Jialei Ding focused on enhancing documentation within the TUDelft-MUDE/book repository, targeting clarity and usability for future contributors. Jialei refined the Jupyter description and adjusted the table of contents formatting directive, ensuring instructional materials were more readable and consistent. The work was performed exclusively in Markdown, leveraging strong documentation skills to deliver low-risk, maintainable improvements without introducing new features or code changes. By providing concise commit messages and clear textual corrections, Jialei supported faster onboarding and easier maintenance for the team. The depth of work was limited to documentation, with no bug fixes or feature development undertaken.
