Worked on stabilizing documentation for the GEOS-ESM/swell repository, focusing on improving link integrity, navigation accuracy, and rendering to enhance user onboarding and contributor experience. Addressed a documentation bug by fixing broken links and correcting sidebar navigation, ensuring users could reliably access model configuration files and Cylc configuration guidance. Improved the readability of the 'history outputs' page by adding a header, which enhanced rendering consistency. All changes were implemented using Markdown and demonstrated strong documentation hygiene, with clear traceability through issue alignment and commit history. The work reduced confusion and support overhead by delivering more accurate and navigable documentation resources.
