Back in Chapter 2, Setting up a Sass and Compass project, we looked at how the config.rb file allows us to
specify any required plugins. We need to ensure that our project ‘knows’ that we require Susy. Open the config.rb file and enter the following line at the top (if it is not there already):
require “susy”
Tip
You can also create a blank project with Susy using the following command (where project-name is the name of the project you wish to create):
compass create project-name -r susy -u susy
This will create a Compass-based project including files such as a _base.scss partial that already contains the required variables and imports them to get started with a Susy layout.
Now our project knows we need Susy, we need to actually include it in our project.
