Jihyeon Jung localized security documentation for Korean users by delivering a complete Korean translation of the Least Privilege Security Guidelines in the mdn/translated-content repository. Using Markdown and leveraging skills in content localization and translation, Jihyeon established a workflow that ensures future multilingual security content can be efficiently produced and maintained. The translation process included initial quality assurance to align with the English source, focusing on accuracy and consistency. This work addressed the need for accessible security guidance for Korean-speaking developers, improved MDN’s internationalization strategy, and laid the groundwork for ongoing translation and technical writing efforts in security documentation.
