Once you've completed these steps, it's time to learn about Jigoshop (if you have no previous knowledge). As a 3rd party plugin, PageLines does not provide official support for Jigoshop itself. However, the masters behind Jigoshop have a vast Knowledgebase for any questions on usability.
To configure Jigoshop for your PageLines Framework powered website, you will find a new option available to you in the "Meta Setup". Here you can define the default section content, layout and other elements that will appear on the templates you've assigned to Jigoshop pages.
