Worked on enhancing the soonklang/Ruby_tutorial repository by updating learner-facing documentation to improve onboarding and resource accessibility. Focused on integrating multimedia presentation materials directly into Markdown files, adding a dedicated Presentation section and a Slide subsection with links to external resources such as Google Drive and YouTube. Emphasized clarity and ease of reference without modifying any code logic or runtime behavior. Utilized Markdown for documentation and ensured that new resources were seamlessly accessible within the tutorial structure. The work centered on documentation skills, prioritizing the user experience for learners seeking supplementary materials, and was delivered through targeted, well-documented commits.
