Developed the foundational scaffolding for the HWTeng-Teaching/202502-Statistics-II repository, focusing on establishing a maintainable project structure to support future feature development and documentation. The work included creating an initial README.md to guide contributors and setting up placeholder files to ensure clear version control practices. Leveraging skills in Git, Markdown, and general project organization, the developer prioritized traceability and onboarding by linking key commits to specific structural changes. While no bugs were addressed during this period, the emphasis on documentation and repository setup laid the groundwork for scalable development and streamlined collaboration in subsequent phases of the project.
