CS 101 - Download and install Git

On Windows (only need to do this once):

Simply download and install Git from their website.

On Mac OS X (only need to do this once):

• Open a command terminal. You can find it by clicking the Launchpad (that multicolor chip in the Dock), any typing terminal in the search field.
• Once you are in the termal (a black window with white text), paste the following command and hit enter:
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
• The install will probably take a good 5 minutes. Once it is done, it will suggest a command to put homebrew in your default path. Copy and paste that command on that same terminal window. When you hit enter, check that it didn't give any error message.
• Still at the command terminal, type in the following command:
  brew install git
• ...or if you missed that part where you add brew to your path, you can try this:
  /usr/local/bin/brew install git
• This install should go quite a bit quicker. Assuming there are no error messages, you can go ahead and quit the command terminal.
