Setting up on MacOS

MacOS comes prepackaged with Vim, but the version can be outdated. There are a few ways to install a fresh version of Vim, and this book will cover two. First, you can install Vim using Homebrew, a package manager for MacOS. You'll have to install Homebrew first, though. Second, you can download a .dmg image of MacVim. This experience would be more familiar because Mac users are used to the visual interface.

Since this book covers interactions with the Command line, I recommend taking the Homebrew route. But you're welcome to go forward with installing the image if interacting with the Command line does not interest you.
