Ruoqi Liu enhanced the HealthRex/CDSS repository by restructuring its documentation to improve clarity and onboarding efficiency. Focusing on the README, Ruoqi introduced a dedicated 'Test' section that outlines the current testing approach, replacing an outdated header to better reflect actual practices. The work, implemented using Markdown and Git for version control, addressed documentation hygiene rather than code-level features or bug fixes. By aligning the documentation with the team’s workflow, Ruoqi reduced potential miscommunication for developers and QA engineers. The updates support long-term maintainability and ensure that new contributors can quickly understand and follow the project’s testing standards.
