During October 2025, Andrey Larkov consolidated and updated deployment and upgrade documentation for VMCluster and VMAlert (version 1.3.0) in the k0rdent/docs repository. He focused on aligning operational procedures with the latest cluster topology and versioned resources, clarifying VictoriaMetrics storage requirements and updating KOF resource specifications. Using Markdown and technical writing skills, Andrey ensured the documentation reflected current architecture and release notes, enhancing traceability across commits. While no major bugs were addressed, minor documentary fixes improved the accuracy of upgrade notes. The work provided clear, maintainable guidance that reduced deployment risk and supported smoother onboarding for engineering teams.
