Worked on enhancing the documentation for the OpenBMB/UltraRAG repository, focusing on UltraRAG 2.0’s Chinese README to improve clarity and accuracy for Chinese-speaking users. The contribution involved technical writing and documentation skills, using Markdown to update and clarify the framework’s capabilities and features in line with recent developments. By refining onboarding materials, the work aimed to reduce confusion and support needs for new users and developers. The changes were committed with traceability in mind, supporting future review and iteration. This effort laid a foundation for improved cross-language accessibility and smoother onboarding within the UltraRAG 2.0 open-source project.
