Dec 1, 2024December 2024 monthly summary for UML-Cyber-Security/CCDC_Practice_Infrastructure: Delivered end-to-end documentation improvements to support Windows DNS deployment and KeyCloak usage. Converted the Windows DNS placeholder into a complete DNS.MD with installation steps and DNS Manager configuration, and aligned KeyCloak installation guidance with consistent Docker terminology to improve readability. These efforts enhance onboarding, reduce setup friction in practice environments, and improve maintainability of infrastructure docs. Demonstrated strong collaboration with documentation governance, precise Markdown editing, and attention to naming conventions across tech stacks.
