During November 2025, Minwoo Choi contributed to the koreader/koreaderhub.io.git repository by initiating Korean translations for the KOReader User Guide. Leveraging PO files and the Weblate platform, Minwoo established a localization workflow that enables ongoing translation management and progress tracking. Although the initial delivery covered 11 percent of the guide’s strings, this work laid the foundation for broader Korean-language support and future quality assurance. Minwoo’s efforts focused on documentation, localization, and translation, directly improving accessibility for Korean-speaking users and supporting KOReader’s market expansion. The approach emphasized maintainability and traceability, with clear documentation and integration of translation management tools.
