Worked on the alibaba/ROLL repository to enhance project documentation and streamline the onboarding process. Focused on reorganizing and consolidating documentation using Markdown, introducing a central index and improving navigation to support both English and Chinese users. Developed a comprehensive installation and setup guide covering Docker-based and custom environments, including detailed instructions for model checkpoint format conversion. Applied configuration and documentation management skills to refactor README files and configuration guides, ensuring consistency and maintainability across multilingual references. These efforts clarified quick-start paths, improved discoverability, and contributed to faster onboarding while reducing support demands for new contributors and users.
