Worked on the GyldendalDigital/kobber repository to streamline developer onboarding by overhauling the local development setup and documentation. Focused on consolidating setup instructions, specifying the required Node.js LTS version, and introducing Corepack enablement guidance to ensure consistent environments across contributors. Enhanced the README with a Storybook quick-start section to accelerate component development and clarified Vite alias usage to minimize environment-related issues. Utilized JavaScript, Markdown, and Shell scripting to deliver these foundational improvements. The work did not include customer-facing features but laid the groundwork for faster, safer contributions by reducing ramp-up time and improving reliability for new developers.
