+Overview
+========
+
+Backbone.Shard is a variation on a Subset taken from different perspective. 
+Shard was built as a simple "persistent filter" for collections; it can 
+help grouping and displaying items of certain kind based on your filter 
+function. I know it works for me, but your mileage may vary.
+
+Usage
+=====
+
+It's easy if you're familiar with Backbone.Collection since Shard shares 
+with it most of the methods marked **Underscore methods** in the 
+`documentation <http://backbonejs.org/#Collection-Underscore-Methods>`_::
+
+  var shelf = Backbone.Shard({
+    collection: books,
+    filter: function(book) { return task.get('read'); }
+  });
+  
+  read.each(...);
+  read.pluck(...);
+
+You can add/remove models or reset *the original collection* and Shard will 
+honestly try to keep up with it, but currently Shard itself has no methods 
+such as add/remove/reset.
+
+Events work and respect your filter function::
+
+  shelf.on('add', doSomething);
+  collection.add({read true}); // this will call doSomething
+  collection.add({read: false}); // this won't
+
