Worked on the nf-core/rnaseq repository to enhance project documentation and maintainability by updating the CHANGELOG.md file to reference a pull request that removed duplicated content from the README.md. Focused exclusively on documentation improvements, the work aimed to improve traceability between pull requests and release notes, supporting clearer audit trails and more efficient onboarding for new contributors. Leveraged skills in Markdown and Git version control to ensure documentation aligned with project standards. No code changes or bug fixes were introduced during this period, reflecting a targeted approach to documentation quality and process transparency within the collaborative bioinformatics workflow.
