During May 2025, Hao contributed to the bytedance/deer-flow repository by expanding its documentation to support Spanish and Russian, enhancing accessibility for a broader user base. Hao localized the main README, integrated links to the new translations, and refined the DeepWiki badge in the German README to improve discoverability and global reach. The work focused on documentation internationalization using Markdown, with careful attention to cross-repository consistency and accessibility standards. By laying the groundwork for future localization and aligning multilingual content, Hao strengthened global onboarding and collaboration, demonstrating depth in documentation management and internationalization practices within a short project period.
