Kaychn focused on improving the Performance API documentation within the lynx-family/lynx-website repository by removing an unnecessary internal link from both the English and Chinese versions. This targeted documentation cleanup, implemented using Markdown, aimed to declutter navigation and reduce redundancy, making it easier for developers to find relevant information. By addressing both language versions, Kaychn ensured consistency and supported localization efforts. The work demonstrated attention to documentation hygiene and a methodical approach to content management. Although the scope was limited to a single feature, the update contributed to a more streamlined developer experience and facilitated faster onboarding for engineers.
