-  Grouping: (optional): 
+
+  	Notes: 
+    To influence ordering, assign an optional 'weight' meta-data value of between of 0 and 100 to each 
+	page/post. The greater the weight value, the higher the order priority when listing pages. Pages/posts
+	without weight values assigned default to a weight value of 0.
+
+	Grouping: (optional): 
   	assign the 'group' variable to constrain the list to only pages/posts
   	in the given group. Note you must define the group manually in the page/post
   	meta-data to use this feature.
   	Grouping is mainly helpful for non-post pages.
   	If you want to group posts, it's easier/better to tag them, then pass the tagged posts array.
   	i.e. site.tags.cool_tag (this returns an array of posts tagged: cool_tag)
