    Git is a tool that helps you track changes in your code over time. It keeps a record of everything you’ve done so you can go back, fix mistakes, or work with others without messing things up.

    When you’re writing code, things change fast. You add new features, fix bugs, or remove things that didn’t work. Without a system, it’s easy to lose track. Git solves that problem. It saves “snapshots” of your project as you go, so you can see what changed, when it changed, and who changed it.

    You don’t save your whole project again and again. Instead, Git only saves the differences. These are called commits. Each commit is like a small message saying what you did, and it connects to the previous one. Over time, they build a full timeline of your project.

    One of the best things about Git is that it works well with teams. Everyone can work on the same project without overwriting each other’s code. You can even create your own copy, make changes, and then bring it back in when it’s ready. This is called branching and merging, and it’s a big reason why developers use Git every day.

    Git runs from the command line, but there are apps that make it easier if you prefer using buttons. Most people also use Git with GitHub or other services that let you store your code online, so you can back it up, share it, or collaborate with others.

    Git isn’t just for experts or big teams. It’s useful for solo projects too. Once you get used to it, you’ll wonder how you ever worked without it. It keeps your work safe, organized, and easy to manage, no matter how simple or complex the project is.
