Contributed to the justjavac/deno-docs repository by developing comprehensive cross-platform installation instructions for Deno using npm. The work focused on enhancing documentation quality in Markdown, providing explicit npm commands tailored for Windows, macOS, and Linux users. Detailed platform-specific performance caveats were included to set clear user expectations and guide installation choices. This documentation update offered a reliable alternative installation method, improved onboarding for new users, and reduced support friction by clarifying potential issues. The approach emphasized version-controlled content updates and cross-platform guidance, demonstrating strong skills in technical writing and documentation maintenance within the npm and Deno ecosystem.
