Worked on the XTLS/Xray-docs-next repository to enhance the accuracy and clarity of DNS configuration documentation for Russian language settings. Focused on documentation cleanup by removing an unnecessary 'tag' field, this update aligned the RU DNS docs with localization guidelines and reduced ambiguity for Russian-speaking users. The work involved careful use of Markdown for documentation and Git for version control, ensuring traceability through a dedicated commit. By addressing this documentation bug, the developer contributed to clearer guidance for users, minimized potential support issues, and improved maintainability of the documentation, demonstrating attention to detail and effective cross-functional collaboration within the project.
