Worked on the hacks-guide/Guide_Wii repository to improve documentation quality by addressing broken internal links related to the Korean Kii/Error 003 section. Focused on enhancing navigability and accuracy, the developer identified and fixed link integrity issues across multiple Markdown pages, ensuring that readers could access the correct sections without encountering dead ends. The solution was implemented through a single, traceable commit, which consolidated all necessary changes for reproducibility. Leveraging skills in technical writing and documentation, the work reduced potential support queries and improved onboarding for new users, demonstrating attention to detail and a methodical approach to maintaining technical documentation.
