During November 2025, Hoang contributed Vietnamese translations to the KOReader User Guide in the koreader/koreaderhub.io.git repository, focusing on improving accessibility for Vietnamese-speaking users. Using a Weblate-driven workflow, Hoang translated 229 out of 1,947 strings, reaching 11.7% coverage and establishing a scalable process for ongoing localization. The work centered on documentation, localization, and translation skills, leveraging PO files to manage and deliver user-facing content.
