Worked on the OpenCSGs/csghub repository to enhance onboarding and developer experience by delivering a comprehensive multilingual documentation update. Focused on improving clarity and accessibility, the work included refining Docker deployment instructions, streamlining the features overview, and integrating demo resources to support faster evaluation. Addressed setup and migration processes by correcting links and updating guidance across English, Japanese, and Chinese documentation using Markdown and technical writing skills. A minor framework refactor simplified the presentation of key features, improving maintainability. The changes targeted documentation accuracy and cross-language usability, resulting in a more robust onboarding process for new and existing contributors.
