Worked on the Icinga/icinga2 repository to enhance documentation, focusing on improving installation and configuration references as well as migration guidance. The approach centered on updating Markdown files to ensure all URLs were current and formatting was consistent, which improved clarity for users. Migration documentation was expanded to explicitly address Nagios, including a clear note on the applicability of the Icinga 1.x migration path. Link management was a key aspect, with obsolete and broken links identified and corrected to maintain documentation integrity. These updates established a more reliable baseline for user onboarding and migration workflows, emphasizing maintainability and accessibility.
