Onitsuka contributed to the justjavac/dify-docs repository by focusing on improving the accuracy and consistency of multilingual documentation. During the month, Onitsuka identified and corrected a typographical error in the spelling of "PostgreSQL" across English, Japanese, and Chinese installation guides, ensuring that deployment instructions for self-hosted environments were clear and aligned with standard database terminology. The work involved careful editing of Markdown files and attention to detail in documentation practices. While the contribution addressed a single bug rather than new features, it enhanced the reliability of deployment guidance and reduced the risk of user confusion across multiple language versions.
