Worked on the gl-inet/docs4.x repository to deliver targeted documentation improvements focused on the Community and Connectivity Guides. The approach emphasized content editing and technical writing, with particular attention to localization for Japanese users and enhancing overall usability. Updates included translation enhancements, typo corrections, and the addition of an interface guide image to clarify Ethernet and repeater setup instructions. Markdown was used to ensure consistency and maintainability across the documentation. These changes improved user onboarding and reduced potential confusion, aligning the content with quality standards and laying the groundwork for more accessible, accurate, and complete documentation for end users.
