Worked on restructuring documentation for the soonklang/Ruby_tutorial repository, focusing on improving the organization and clarity of onboarding materials. Updated the README.md and SUMMARY.md files using Markdown, renaming the main title from "Ruby Tutorial" to "Page" and revising navigation links to match the new structure. This documentation update enhanced navigation and discoverability for both new contributors and users, streamlining the onboarding process. The approach emphasized clear documentation practices and laid the foundation for consistent future updates. No bugs were addressed during this period, with all efforts concentrated on documentation structure and content alignment to support evolving project requirements.
