Worked on enhancing the copilot-cli repository by improving the clarity and accuracy of documentation related to PAT authentication. Focused on refining the README, the developer corrected typos and adjusted punctuation to make authentication instructions more accessible for users. This documentation update, delivered through two targeted commits, aimed to streamline the onboarding process and reduce potential support queries. The work demonstrated attention to detail in user-facing content and effective use of Markdown for technical writing. Collaboration was managed through Git, emphasizing version control best practices. No new features were added, but the bug fix contributed to a smoother user experience.
