Worked on the astral-sh/ruff-action repository to enhance documentation clarity and version accuracy for users. Focused on updating the README file using Markdown to specify ruff-action version 4.0.0, replacing all previous references to version 3. This targeted documentation improvement aimed to reduce user confusion and support overhead by aligning installation instructions with the actual release. Employed version control best practices with Git to ensure traceability through commits and pull requests. The work demonstrated attention to documentation standards and version pinning, resulting in smoother onboarding and clearer guidance for users, though no bug fixes or additional features were delivered during this period.
