Worked on the OpenBMB/UltraRAG repository to enhance documentation quality and onboarding clarity. Focused on refining the English README by removing duplicate Docker startup instructions and aligning content with the Chinese version, which improved cross-version consistency and reduced potential onboarding issues. Applied technical writing and version control skills to ensure documentation updates were precise and traceable. Used Markdown to implement grammar corrections, such as adding missing punctuation in the installation section, thereby improving readability and professionalism. The work addressed documentation gaps rather than core features or bug fixes, contributing to a smoother user experience for both English and Chinese-speaking developers.
