Worked on improving the documentation quality for the haiwen/seafile-admin-docs repository, focusing on enhancing the accuracy of setup instructions. Addressed a documentation bug by correcting a typographical error, changing 'Docer' to 'Docker' to ensure users receive precise guidance when configuring Docker environments. The work involved careful review and editing of Markdown files, emphasizing clarity and reducing potential onboarding issues for new users. By refining Docker-related terminology, the update aimed to minimize confusion and decrease support requests related to setup errors. The contribution demonstrated attention to detail in documentation and a commitment to maintaining high standards in technical communication.
