Worked on the OpenCSGs/csghub repository to deliver a targeted documentation update focused on user authentication workflows. The contribution centered on enhancing the Chinese-language documentation using Markdown, clarifying third-party login limitations, and specifying requirements for username updates to align with security and compliance standards. The update also transparently noted that password write-back integration with Casdoor remains incomplete, providing clear guidance for both users and developers. By improving localization and addressing common support issues, the work aimed to reduce user friction and support tickets. No code changes were made to the public API, with all improvements concentrated in documentation quality and clarity.
