Worked on updating lab documentation in the kakaocloud-edu/tutorial repository to align with the latest Kubernetes v1.28 release and revised storage recommendations. Focused on improving onboarding and curriculum reliability by editing Markdown files, specifically updating Lab02.md for version compatibility and adjusting Lab03.md to recommend a 30 GB storage volume instead of 10 GB. Emphasized clear documentation practices to ensure traceability and facilitate future audits or rollbacks. Utilized skills in documentation and Markdown to deliver changes that reflect current platform capabilities, supporting both instructors and students in maintaining up-to-date lab environments and enhancing the overall educational experience.
