Git and GitHub

Git manages local version control while GitHub provides the cloud infrastructure for 100 million developers to collaborate.

Linus Torvalds created Git in 2005 to manage the Linux kernel source code. Today, GitHub hosts over 420 million repositories, serving as the primary hub for major open-source projects like React and VS Code. Developers use Git commands (commit, push, pull) to track incremental changes locally. GitHub adds the essential social layer: pull requests for code reviews, Actions for CI/CD pipelines, and Issues for bug tracking. This combination ensures code integrity and team velocity across distributed environments.
