Rijad Ext updated the onboarding documentation for the garden-io/garden repository, focusing on the "Your first project" tutorial to align with recent v14 manifest changes. The work involved revising Markdown files to rename the manifestFiles key to manifestTemplates and introducing a hostname variable for local environment configuration. By ensuring the tutorial accurately reflected the latest project initialization and action configuration processes, Rijad improved the clarity and reliability of user onboarding. The contribution centered on documentation skills and Markdown, with careful attention to technical accuracy. The scope was focused, addressing a single feature update without bug fixes, demonstrating depth in documentation maintenance.
