Worked on the nextflow-io/training repository to improve onboarding documentation for new users. Focused on enhancing the clarity of the Hello World tutorial by correcting a typo and updating a code sample filename to better reflect the intended context. Used Markdown to ensure documentation consistency and maintainability, applying careful attention to detail in both descriptive text and code references. The work addressed a specific documentation bug, contributing to a smoother onboarding experience and reducing confusion for beginners. Emphasized traceability by linking the fix to a tracked issue, demonstrating a methodical approach to documentation quality and collaborative development practices within the project.
