Pages
From Shopify Wiki
The liquid variable pages refers to the pages of your shop.
By calling a page's handle on pages you will receive the page.
Example usage:
<h1>{{ pages.about.title }}</h1>
<p>{{ pages.about.author }} says...</p>
<div>{{ pages.about.content }}</div>
This lets you print the content of your page with handle about on any page of your Shopify store. Even in the layout! This is a great way to let a shop-owner add his own text to sections of the design without exposing him to editing the HTML directly.
NOTE: You cannot iterate over pages. Your best bet if you need to do this is to use a linklist.
