During February 2025, Nini Mg established foundational onboarding documentation for the HWTeng-Teaching/202502-Statistics-II repository by authoring a comprehensive README.md. The README introduced the project’s purpose, outlined the onboarding process, and set expectations for future content, aiming to streamline the experience for new users and contributors. Nini focused on improving repository discoverability and knowledge transfer, leveraging Markdown for documentation and Git for version control. No bug fixes were addressed during this period, as the primary engineering effort centered on documentation structure and maintainability. The work provided a clear entry point for future development, but did not involve deeper technical implementation.
