Worked on improving documentation reliability for the microsoft/AI-For-Beginners repository by addressing critical issues with README links related to TensorFlow resources and setup lessons. Focused on enhancing learner onboarding and reducing navigation errors, the work involved identifying and correcting broken URLs to ensure that users could access the correct GitHub locations. Utilized Git for precise version control and Markdown for documentation updates, maintaining clear commit history to support future maintenance and auditability. The approach emphasized technical writing best practices, resulting in more dependable learning resources and streamlined navigation, without modifying code or adding new features, but improving overall repository quality.
