Worked on the gl-inet/docs4.x repository to modernize and standardize developer-facing documentation for GL-iNet routers, focusing on improving onboarding and reducing support overhead. Delivered a comprehensive rewrite of setup guides and VPN configuration instructions, unifying content across models such as MT3000, Slate AX, Puli AX, and Spitz AX. Applied technical writing and documentation skills using Markdown to reorganize content, enhance navigation, and add product overview images for better usability. Addressed documentation bugs by correcting terminology, fixing broken links, and resolving formatting issues, particularly in the GL-MT3000 Router User Guide, resulting in clearer, more consistent, and maintainable documentation.
