Zidane Bagus Pratama developed the initial Indonesian localization for the KOReader User Guide, focusing on expanding accessibility for Indonesian users. Working within the koreader/koreaderhub.io.git repository, Zidane established a Weblate-driven workflow to manage ongoing translation updates and ensure traceability throughout the process. Using PO files and leveraging skills in documentation, i18n, and localization, Zidane delivered the first set of translated strings and documented the translation pipeline for future scalability. Although the coverage reached 1.5% during the period, the work laid a foundation for continuous localization, enabling broader adoption and improved user experience in Indonesian-language contexts.
