Worked on establishing the initial development scaffold for the Groupe 5 section within the fabienlierville/di24-cours-git repository, focusing on creating a clear directory structure and providing placeholder assets to streamline future feature development. The approach emphasized incremental delivery, with multiple Git commits reflecting iterative updates and disciplined version control practices. HTML and basic file organization skills were applied to introduce and later refine an index.html starting point, ultimately removing it to optimize the scaffold. This foundational work aimed to reduce onboarding time for new contributors and set up a maintainable structure, supporting efficient collaboration and future enhancements for the project.
