A LuxDevHQ data engineering student explains why Git and GitHub are fundamental tools for modern code and data work. The guide covers core concepts like version control, which tracks changes and enables collaboration on long projects. This foundation is essential before diving into practical setup steps.

The article walks through initial setup on macOS, from installing Git via the terminal to configuring user details. It then details connecting to GitHub using SSH keys for password-free access. This secure method streamlines the workflow, allowing students to focus on building their skills rather than managing credentials.

For actual project work, the guide covers creating a local repository, tracking changes with git add and git commit, and pushing code to a GitHub remote. It also explains pulling updates for collaboration and viewing project history with git log. Mastering these commands is critical for any aspiring data engineer's toolkit.
