During June 2025, Zhao focused on enhancing the documentation and onboarding experience for the alibaba/ROLL repository. He reorganized project documentation using Markdown and JavaScript, introducing a central index and overhauling navigation to improve discoverability and support both English and Chinese users. Zhao developed a comprehensive installation and setup guide covering Docker-based and custom environments, including detailed instructions for model checkpoint format conversion. His work emphasized configuration clarity and documentation management, with targeted refactoring of README and configuration guides to ensure consistency. These improvements streamlined onboarding, reduced support overhead, and provided a more reliable foundation for new contributors and users.
