Igor Ferreira enhanced the aidenybai/react-scan repository by updating its documentation to support Bun users, focusing on improving onboarding and cross-runtime compatibility. He added explicit Bun installation instructions to the README, enabling developers to quickly set up the package using the command 'bun add react-scan.' This update addressed the evolving needs of users adopting alternative package managers and clarified setup steps for new contributors. Igor utilized Markdown for documentation, Git for version control, and demonstrated familiarity with both Bun and NPM workflows. The work was limited in scope but provided clear, targeted improvements to documentation quality and user experience.
