Git & GitHub
The version control foundation every software project is built on.
Git is version control software — it tracks every change ever made to a codebase. Every file edit, every addition, every deletion is recorded with who made it, when, and why. This means any version of the code can be retrieved, compared, or restored at any time.
GitHub is the cloud platform where Git repositories are hosted. It adds collaboration features on top of Git: pull requests for code review, issues for tracking bugs and features, wikis for documentation, and integrations with deployment tools.
Together, Git and GitHub are the foundation of how the software industry manages code. Every project we build lives in a GitHub repository from day one.
Every version of the code is preserved. A change that breaks something can be reversed. Code deleted by accident can be restored. The full history is always there.
Multiple developers work on different features simultaneously in separate branches, then merge changes together cleanly — no overwriting each other's work.
GitHub pull requests let changes be reviewed, discussed, and approved before merging to the main branch. Quality and security checks happen before code is live.
A push to the main branch can automatically trigger a deployment via GitHub Actions and Forge. The path from code review to production is automated.
