It’s crucial to keep your repository clean and focused. Avoid pushing build directories or commented-out code, as they can clutter your project and are recoverable from Git history if needed.

Collaboration is key in any project. Use merge requests to propose changes and have them reviewed by peers. This not only improves code quality but also fosters team knowledge sharing.
