🌿 Version control is time travel for your codebase

Git is the version control system the entire industry converged on — and there is more to it than commit, push, and pull. This category covers branching strategies, rebasing, merging, conflict resolution, hooks, tags, and the internal object model that explains why Git behaves the way it does. Understanding Git deeply prevents disasters and enables confident collaboration.

History

Git was created by Linus Torvalds in 2005 as a distributed version control system for Linux kernel development, replacing BitKeeper after a licensing dispute. Its design emphasized speed, distributed workflows, and data integrity through cryptographic hashing, fundamentally shifting how teams could collaborate on code without a central server dependency. Early adoption by major open-source projects and GitHub's 2008 launch as a web platform democratized Git workflows, making distributed version control the industry standard. Over the past two decades, Git practice has evolved from simple branching strategies (like Git Flow) to lighter models (GitHub Flow, trunk-based development), with tooling maturity enabling advanced workflows such as rebase-first workflows, conventional commits for automation, and CI/CD integration. Today, Git is ubiquitous across software development—from solo projects to massive monorepos—and its internal mechanisms (objects, refs, reflog) remain largely unchanged, underscoring Torvalds's original architectural insight.
