Gustavo Fernandes developed a comprehensive onboarding and contribution guide for the HackYourFuture-CPH/programme repository, focusing on improving clarity for new contributors. He authored detailed documentation in Markdown, outlining project setup using Bash commands such as npm ci, and provided recommendations for VSCode extensions to streamline the development environment. The guide also described the linting workflow and established a clear process for proposing ideas and prioritizing tasks within the project. While the work was limited to a single feature over one month, Gustavo’s contribution addressed a key documentation gap, enhancing the project’s accessibility and maintainability for both current and future collaborators.
