Worked on the Quant_RUC repository to consolidate and enhance documentation and asset management for the Homework/econ/2023200727 directory. Focused on improving long-term maintainability and onboarding by updating the README, standardizing documentation from readme.txt to readme.md, and ensuring accurate ownership attribution. Utilized Git for version control and Markdown for documentation, maintaining a clear commit history to support traceability and auditability. Added a URL reference file and uploaded a certificate image to strengthen documentation assets. No bugs were addressed during this period, as the primary emphasis was on documentation discipline, asset completeness, and governance using text-based documentation skills.
