Worked on the xcp-ng/xcp-ng-org repository to enhance the reliability of upgrade documentation by addressing a dead link issue that previously directed users to an outdated wiki page. The approach involved carefully reviewing the Markdown-based documentation, identifying obsolete references, and updating them to point to current, maintained resources. This documentation improvement aimed to streamline the upgrade process for users, reducing confusion and minimizing potential errors during upgrades. The work primarily utilized Markdown for documentation and required attention to detail in technical writing. By focusing on documentation quality, the changes contributed to a smoother user experience and reduced support overhead for upgrades.
