Version control is the practice of tracking and managing changes to code so that developers can collaborate without overwriting each other’s work, revert to previous states, and maintain a complete history of modifications. Git is the most widely used version control system. Platforms like GitHub and GitLab host Git repositories and add collaboration tools such as pull requests and code reviews. Version control is a fundamental professional development practice that enables safer, more organized website development and maintenance.

FAQs
Questions about Version Control (Git)
What is version control, and what is Git specifically?
Version control is a system for tracking changes to files over time, so previous versions can be reviewed or restored if something goes wrong. Git is the most widely used version control system in web development, letting developers track, compare, and roll back changes to code with a detailed history of what changed and when.
Why does version control matter for a website's codebase?
Without it, a mistake or bad update can be difficult or impossible to undo cleanly, and multiple people working on the same code risk overwriting each other’s changes. Git gives a clear, reversible history, which is especially valuable for custom theme development where small changes can have unexpected effects elsewhere.
Does a WordPress site need Git if it's mostly managed through the dashboard?
Sites relying mainly on plugins and the visual editor get less direct benefit, but any site with custom theme code, like custom PHP templates or functions, benefits significantly from Git tracking those changes. It’s standard practice for professional custom development work, even on a platform as dashboard-driven as WordPress.
