No installation, backend setup, or API tokens are required.</p> <p>It is fully localized in English and Portuguese. I built this purely to give back to the community and help those struggling with their first open-source contributions. Hope it helps someone out there!</p> <p>Live Project: <a href="https://brunnojob.github.io/devstart-lab/" rel="noopener noreferrer">https://brunnojob.github.io/devstart-lab/</a><br> Source Code: <a href="https://github.com/brunnojob/devstart-lab" rel="noopener noreferrer">https://github.com/brunnojob/devstart-lab</a></p> <h1> opensource, #github, #beginners, #webdev </h1> beginners githubactions github opensource
