Worked on the justjavac/dify-docs repository to enhance the accuracy and consistency of multilingual documentation for self-hosted deployments. Focused on correcting a critical typographical error in the installation guides, ensuring the term "PostgreSQL" was used correctly across English, Japanese, and Chinese versions. Utilized Markdown to update documentation and applied attention to detail in aligning terminology with PostgreSQL standards, thereby reducing the risk of deployment errors for users following the guides. Demonstrated proficiency in documentation practices and multilingual content management, contributing a targeted bug fix that improved the reliability of installation instructions without introducing new features during the period.
