Install Homebrew
Also called "Brew." Brew is like the app store for the command line (i.e. your terminal). If you ever need any command-line tool, try installing with Brew before other methods. (ex. brew install name-of-thing)
Install brew by copying and pasting this beautiful code into your terminal:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
