Jialei Ding worked on the TUDelft-MUDE/book repository, focusing on stabilizing and refining the documentation publishing workflow. Using YAML and documentation management skills, Jialei restored the documentation table of contents by reverting unintended changes in the _toc.yml file, which had previously led to premature content exposure and missing sections. To improve publishing accuracy and maintainability, Jialei introduced a conditional publishing block within the YAML configuration, ensuring only intended content is published. This approach reduced the risk of incorrect documentation going live and increased consistency between source files and published docs, demonstrating a methodical and detail-oriented approach to documentation engineering.
