Worked on the scikit-learn/scikit-learn repository to enhance documentation by updating the DOI badge in the README.rst file, ensuring the correct DOI link was displayed for accurate citation. Focused on improving documentation accuracy and usability for users and researchers, the update required careful attention to reStructuredText formatting and adherence to established documentation standards. Utilized skills in documentation and version control to verify the change aligned with project guidelines and supported reproducibility. No codebase modifications were necessary, as the work centered on maintaining high-quality documentation practices and facilitating reliable project citation, ultimately contributing to smoother onboarding and increased user trust.
