Worked on the apache/zeppelin repository to address a critical issue in the Zeppelin tutorial documentation, focusing on improving user onboarding and reducing support friction. The main contribution involved fixing a broken download link for the bank marketing dataset by updating the Markdown documentation and providing clear extraction instructions for the new archive structure. This documentation update ensured that first-time users could reliably follow the tutorial steps without confusion. Emphasizing maintainable repository practices, the work aligned the tutorial with the latest data archive format. The technical approach centered on documentation skills and proficiency with Markdown to enhance the overall reliability of onboarding materials.
