# Git

Git keeps a history of your code, so you can go back to an earlier version, and on Windows it comes as Git for Windows, with Git Bash to type its commands in.

## After this lesson you can

- Name what Git for Windows installs, and say where you type Git commands

## Key takeaways

- Git keeps a history of your project. Each commit is a saved point you can go back to.
- On Windows you install Git for Windows. It brings Git, Git Bash and Git Credential Manager.
- You type Git commands in Git Bash. Each one starts with git, such as git status.

**Windows only.** Think of a video game that saves your progress at checkpoints. If something goes wrong, you go back to the last checkpoint instead of starting over. **Git** does that for your code. It is a **version control** system: it keeps a history of your project, and each saved point, called a **commit**, is one you can go back to.

You will use Git every day in this course, to save your work and to keep a copy of it on GitHub.

## What Git for Windows installs

On Windows, you install **Git for Windows**. One install gives you three things:

| Part | What it does |
|---|---|
| **Git** | The program that keeps your project's history |
| **Git Bash** | The terminal you type Git commands in, and the one you use for the whole bootcamp |
| **Git Credential Manager** | Signs you in to GitHub through your web browser, then remembers you |

You install it in **Setup: Install Git, Git Bash, and connect to GitHub**, later in this topic.

## What Git commands look like

Every Git command starts with `git`, then what you want it to do. You type them in Git Bash, inside your project's folder. Here are the three you will use most, to save a change and send it to GitHub:

```bash
git add -A
git commit -m "Add the shopping list page"
git push
```

`git add -A` gets every change ready to save, `git commit` saves them as one commit with a message that says what changed, and `git push` sends your commits to GitHub. The Working with Git topic explains each step.

**Try it.** After you install Git, open Git Bash and type `git --version`. It prints the version of Git you have, such as `git version 2.56.0.windows.1`.
