Yoshitake Asano enhanced the cloudnativedaysjp/cnd-handson repository by expanding and refining its CI/CD documentation to support CNDS2025 readiness. Focusing on Markdown and technical writing, Asano introduced a new chapter detailing GitOps practices with ArgoCD, aligning terminology and structure to improve onboarding and discoverability for developers. The work emphasized clarity and consistency, standardizing language across documentation and updating repository visibility to streamline adoption of continuous delivery workflows. No bugs were reported during this period, reflecting a focus on depth and quality in documentation rather than code changes, and resulting in more accessible and maintainable technical resources for the project.
