Git Bash is a very popular package for Windows. As the name suggests, it includes not only Git, a Version Control System for tracking code changes, but also Bash, a UNIX command line shell. In this guide, let's install Git Bash to get you up and running with Git!

Before we get started, let's understand why we need to install Git Bash. Couldn't we just use CMD or Windows PowerShell to work with Git?

Git is a combination of command line programs that were built to execute on a Unix environment. Operating systems based on Unix, like Linux or macOS, come with Bash (Bourne Again SHell), which ensures that Git runs smoothly across these systems.

Windows is not included in this list (it's a DOS-based operating system), so it doesn't support Git out of the box. This is solved by — you guessed it! — installing Git Bash, which will provide the necessary emulation to access all the command line tools Git needs. You will also be able to use other useful Bash utilities, such as `ssh`, `cat`, `scp` or `nano`. 

Now that you understand *why* you need Git Bash, it's time to download and install it!

## How to Install Git Bash on Windows

Let's start by downloading the Git Bash executable from the [official website](https://git-scm.com/downloads). You should quickly notice the "download" area on the right.

Once the download is finished, run the installer (make sure you have Windows administrator privileges). After allowing the app to make changes to your Windows device and reading the GNU General Public License, the Git Bash installation wizard will prompt you some questions.

The default options should be fine for most users, but there are a couple of questions worthy of your attention. Let's have a look at these before clicking "Next" blindfold.

### Select Components

On this screen, you can pick the components you would like to install. For instance, you can add the "Additional Icons" component if you want to have a Git Bash shortcut on the desktop.

### Choosing the Default Editor used by Git

You can use any text editor with Git. For historical reasons, Vim is the default option, but even the wizard recommends switching to a more modern GUI editor, like [VS Code](https://code.visualstudio.com/) or [Sublime Text](https://www.sublimetext.com/). 

We also suggest you pick a different one, unless you're comfortable with Vim already!

### Adjusting the Name of the Initial Branch in New Repositories

When you initialize a new Git repository, you will have an initial branch created for you. The default branch name is "master"; because of the negative association with this word, that is bound to change soon — many organizations in the Git ecosystem, like [GitHub](https://github.com/github/renaming) or [GitLab](https://about.gitlab.com/blog/2021/03/10/new-git-default-branch-name/), are replacing "master" with "main".

While this won't affect existing repositories, you may want to select "Override the default branch name for new repositories" and type a different default branch name for new projects.

After carefully reviewing these questions, proceed until you complete the Setup Wizard. 

If you leave "Launch Git Bash" selected, the Wizard will finish by launching the Git Bash Terminal. Otherwise, you can launch Git Bash from the Windows Start Menu or by right-clicking any folder and selecting the "Git Bash Here" option.

Once in the command line, you can confirm Git is installed by typing `git --version` (this will tell you the currently installed version). Git will now also work on CMD and Windows PowerShell.

We're almost there! There's just one more step...

### Defining the Username and Email Address

Before we can start working with Git, we still need to define our username and email address. We will only be able to add commits after setting these options.

To set the username:
`git config --global user.name "FIRST_NAME LAST_NAME"`

To set the email address:
`git config --global user.email "MY_NAME@example.com"`

You can always review all the configuration items by typing:
`git config --list`

If you prefer, you can also edit these settings with a text editor. Git Bash installed `nano`, so we could type `nano ~/.gitconfig` to make some changes directly in the Terminal. When you're done, press CTRL+X to exit.

We're all set. Hooray! 🎉
