Graczyk focused on expanding KOReader’s accessibility by localizing the KOReader User Guide for Polish users in the koreader/koreaderhub.io.git repository. Using PO files and leveraging Weblate for translation management, Graczyk translated 12.2% of the guide’s strings, establishing a scalable workflow for ongoing localization. This work aimed to improve onboarding and reduce language barriers for Polish-speaking users, laying the foundation for broader adoption in that community. While no bugs were fixed during this period, the effort demonstrated effective use of localization and translation skills, with a clear technical approach that addressed product usability and internationalization requirements for future releases.
