Worked on the MicrosoftDocs/defender-docs repository to deliver comprehensive documentation updates for Linux Defender for Endpoint, focusing on FAPolicyD compatibility for RHEL and Fedora systems. Used Markdown to clarify support scope, prerequisites, and fanotify exception handling, ensuring that administrators understand the requirement for mdatp health to be true for compatibility. The documentation improvements addressed deployment readiness and reduced confusion around fapolicyd exception communication, directly supporting smoother onboarding for Linux endpoint administrators. All changes were tracked through multiple commits, emphasizing traceability and clarity. The work demonstrated strong documentation skills and a methodical approach to technical communication within open-source environments.
