Version control is a system that tracks changes to your files over time, letting you see what changed, who changed it, and why. Whether you're writing code, managing documents, or collaborating with others, version control creates a complete history you can return to if something goes wrong. Instead of keeping dozens of copies with names like "final_v2_REAL.doc," version control stores one current version and remembers every edit that led to it.
The articles here explain how version control prevents lost work, lets multiple people edit the same project without overwriting each other's changes, and makes it straightforward to undo mistakes. You'll learn what version control actually does, how it differs from cloud storage or shared folders, and which tools work best depending on whether you're working solo or as part of a team.
