Worked on the rucio/documentation repository to enhance the contributor onboarding experience by updating and clarifying the Contributing Guidelines. Focused on documentation and technical writing using Markdown, the developer removed outdated references to a deprecated autotest tool, ensuring that new contributors receive accurate and current information about testing workflows. This targeted update addressed Issue 8328 and aimed to prevent confusion, reduce support overhead, and maintain alignment with the project's present tooling. No bug fixes were required during this period, as the primary effort centered on improving maintainability and clarity within the documentation to support a smoother onboarding process for future contributors.
