Only Windows users not using Eclipse as their IDE will need to intall Git manually.
Eclipse uses its own version of Git, and thus does not require Git to be installed.
Meanwhile, macOS should come with Git, and Linux operating systems should have easy access to git via the built-in package manager, so this guide is only for Windows. (If you're using Linux, we'll assume you know where to look if you need help installing Git.)
Note that most of the options in this process don't matter for this class. The screenshots in the walkthrough below show settings for one example installation, but you may choose other options unless we explicitly state otherwise in the steps below. Additionally, if there are any screens or settings in the installer that are not included in this guide, leaving those settings default should be fine (alternatively, you may apply common sense to choose those options).
Download and run the Git for Windows installer from this page.
Accept the license by clicking "Next >".
On the next screen, choose any additional components you want, or just leave them default. None are required for the class, but none take any significant disk space, so it's fine to do whatever.
On the next screen, you can choose a default text editor for Git. We won't need to run Git from command line, so Git should never actually use this setting, so it's again safe to select anything here; if you don't have any of the listed programs installed already, we recommend just selecting the one for Nano.
On the next screen, choose which Git tools will be available from command line. We strongly recommend you choose the default option, as shown below:
On the next screen, choose an HTTPS backend. This choice shouldn't matter, so the default is fine.
On the next screen, choose how line endings will be treated. We strongly recommend choosing the default option, since anything else will likely produce formatting errors between operating systems.
On the next screen, choose which terminal emulator Git Bash will use. The two options have slightlly different behaviors and configuration options, but both are functional, so it doesn't matter which you choose here.
The last screen presents some more miscellaneous options. There isn't much reason to disable any of these, so you can just leave them enabled (or disable them if you want.)
Afterwards, click "Install", and the installer should install Git. When it finishes, you can close it without starting Git Bash or viewing the README file.
