Worked on enhancing course project documentation in the umnooob/course-demo repository by introducing a Retrieval-Augmented Generation (RAG) topic entry and providing a direct GitHub repository link within the 课程大作业.md file. Focused on improving clarity around deadlines and submission requirements to better support student onboarding and assessment alignment. Utilized Markdown for documentation and applied Git version control to ensure traceable updates. The work demonstrated attention to cross-language documentation, accommodating both Chinese and English contexts. No bugs were addressed during this period, with efforts concentrated on documentation quality and process transparency to facilitate smoother project guidance and evaluation readiness.
