Worked on the koreader/koreaderhub.io.git repository to deliver the initial Catalan localization of the KOReader User Guide, translating 231 out of 1951 strings and increasing localization coverage to 11.8 percent. Leveraged PO language files and a Weblate-based workflow to manage translation and content updates, ensuring translation integrity through quality assurance checks. Focused on content management, documentation, and localization to improve accessibility for Catalan-speaking users and lay the groundwork for future language expansion. No major bugs were addressed during this period, with efforts concentrated on expanding internationalization and establishing a sustainable translation process for ongoing documentation updates.
