Worked on the nesaorg/nesa repository to improve the reliability of contest documentation by addressing a broken hyperlink in CONTEST.md. Focused on documentation hygiene, the developer identified and corrected the path to Attack_Paper.pdf, ensuring that users could access the intended resource without confusion. The fix involved a precise Git-based patch, updating the link from an incorrect directory to the correct main branch location. This change was validated through repository documentation build processes and manual link testing. The work demonstrated attention to detail with Markdown editing, basic link validation, and version control, ultimately reducing potential user support issues related to documentation.
