Worked on enhancing the NADOOIT/NADOO-Wiki repository by delivering comprehensive documentation improvements focused on exercises and CI/CD concepts. Consolidated glossary updates across branch and conflict exercise entries, introduced a new CI/CD glossary term, and refined test placeholders to improve the reliability of glossary tests. Utilized Markdown for all documentation changes, emphasizing clarity and maintainability. Updated the README to better support developer onboarding and knowledge transfer, ensuring that new contributors can more easily understand CI/CD processes. The work prioritized documentation quality and maintainability, aiming to accelerate CI/CD adoption and reduce future support needs through clear, well-structured technical writing.
