What is dio-lab-open-source?

This repository is the hands-on lab for a course called "Contributing to an Open Source Project on GitHub," offered by Digital Innovation One (DIO), a Brazilian technology education platform. The project exists so students can practice the full open-source contribution workflow in a safe, guided environment, without needing a complex codebase to navigate. The site is a simple webpage that collects contributor profile cards from everyone who completes the lab. It is built with plain HTML, CSS, and JavaScript, organized under a docs/ folder with separate subdirectories for stylesheets and scripts. A live hosted version of the page is linked in the README so participants can see what a finished contribution looks like before they submit their own. The contribution flow is intentionally simple. A participant forks the repository, adds their own GitHub profile to the contributor list, and opens a pull request back to the main repo. This single action gives students direct experience with forking, branching, committing, and the pull request review process. Because the change required is tiny, the focus stays entirely on the mechanics of collaboration rather than on writing code. The README is written in Portuguese, which reflects the DIO platform's primary audience. Despite the language barrier, the structure of the code itself is easy to follow, and the file layout is clearly organized. The tech stack is entry-level by design: HTML, CSS, and JavaScript, nothing more. If you are going through the DIO curriculum or simply want a low-stakes first open-source contribution, this is a practical starting point. The scale of the contribution required is minimal, but the GitHub skills you practice here apply to every open-source project you will encounter later.
