Worked on the thoughtbot/guides repository to consolidate and enhance JavaScript and TypeScript documentation. Merged separate JS and TS guides into a unified Markdown-based resource, streamlining onboarding for developers and reducing future maintenance. Updated deprecated links throughout the documentation to ensure references remain current, and reorganized the README to improve navigation and discoverability. Focused on content management and documentation quality, the work addressed link rot and lowered the overhead associated with maintaining multiple guides. By consolidating related documentation and improving structure, the changes made it easier for contributors to find information and maintain consistency across the repository’s technical resources.
