   This snippet is used to showcase each product during the loop,
   'for product in collection.products' in collection.liquid.
 
-  This example has three products per column on desktop, two on
-  our medium breakpoint, and a single row on small screens.
+  A liquid variable (grid_item_width) is set just before the this
+  snippet is included to change the size of the container.
+  Once the variable is set on a page, all future instances of this
+  snippet will use that width. Overwrite the variable to adjust this.
