Worked on the oxygenxml/userguide repository to enhance documentation quality and maintainability. Focused on DITA-based documentation, the developer addressed a bug by correcting typographical errors, clarifying the use of CSS string-set for headers and footers, and refining code snippet markup and cross-references to improve readability. Asset management was also improved by removing an orphaned image file and deleting unused resources, reducing maintenance overhead. All changes were implemented with a strong emphasis on documentation best practices and traceability, following established quality assurance standards. The work leveraged skills in documentation and DITA, contributing to clearer user guides and streamlined future updates.
