Worked on the Icinga/icinga2 repository to maintain and improve project documentation, focusing on streamlining the installation guide for better onboarding and reduced support needs. The work involved removing outdated RHEL 7 installation steps and updating attribution in the AUTHORS file to reflect current contributors. Using Markdown and documentation best practices, the developer clarified installation instructions to align with supported operating systems, minimizing confusion for new users. No bug fixes were addressed during this period, as the primary emphasis was on documentation quality and maintainability. The changes aimed to simplify ongoing maintenance and ensure accurate, up-to-date guidance for the community.
