Let's get ready to use Bourbon, Bitters, and Neat. First, we need to install a couple of things.
In a handful of situations, we'll perform tasks on the Command Line. In case the CLI is all Greek to you, I recommend you have a look at our Command Line 101 to conquer your fear.
If you want to avoid the Command Line by all means (and you happen to work on a Mac), you might want to get an app like CodeKit.
There are different ways to get your hands on the framework - for example using Bower, npm, or Ruby Gems. For this tutorial, we chose to use the latter.
Installing Ruby Gems
Although Ruby has become a very widespread language in recent years, let's make sure and check if Ruby is installed on your machine. Open your command line application (Terminal.app on a Mac and, e.g., the Git Bash app on Windows) and execute the following command:
$ ruby --version
You should get something like this in return:
ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-darwin16]
If this should prove that Ruby is not installed on your system, there are tons of tutorials on how to do this; e.g. the Installing Ruby chapter on the official Ruby website.
Now, let's install the whole pack:
$ gem install bourbon neat bitters
Note that you'll probably have to prepend the command with the sudo keyword ("sudo gem install...") so the installation can run with administrator privileges.
