During December 2024, Yupi focused on enhancing the documentation for the Whisky-App/whisky-book repository. Yupi improved clarity and maintainability by editing Markdown files, correcting grammar and punctuation in user-facing messages, and renaming content to better reflect its purpose. The work included fixing a URL-encoded link in SUMMARY.md related to METAL GEAR SOLID V: THE PHANTOM PAIN, ensuring accurate navigation for users. Although no bugs were addressed, Yupi’s efforts centered on documentation quality, leveraging skills in technical writing and Markdown. The depth of work was limited to a single feature, emphasizing incremental improvements rather than broad architectural or codebase changes.
