Worked on enhancing the documentation for the Checkmk/checkmk-docs repository, focusing on the integration of the OpenTelemetry TUI Collector. The update introduced an explicit reference to the collector, improving clarity and completeness for users navigating the telemetry section. By aligning cross-references and refining onboarding guidance, the documentation now supports faster user adoption and reduces the likelihood of support queries. The work was implemented using AsciiDoc and leveraged technical writing and documentation skills to ensure accuracy and usability. This targeted documentation feature addressed a specific gap, resulting in a more cohesive and accessible resource for users working with telemetry tools.
