-Usage
------
+Add an alias for the query builder, you can change this alias to your own preference:
 
-Tell your model to use the MongoDB model and a MongoDB collection (alias for table):
-    
-    use Jenssegers\Mongodb\Model as Eloquent
-    
-    class MyModel extends Eloquent {
-    
-        protected $collection = 'mycollection';

+Eloquent
 --------
 
+Tell your model to use the MongoDB model and set the collection (alias for table) property:
+    
+    use Jenssegers\Mongodb\Model as Eloquent
+    
+    class MyModel extends Eloquent {
+    
+        protected $collection = 'mycollection';
+    
+    }
+
+**Everything else works just like the original Eloquent model.**
+
+Query Builder
+-------------
+
+The MongoDB query builder allows you to execute queries, just like the original query builder (note that we are using the previously created alias here):
+
+    $users = MDB::collection('users')->get();
+    $user = MDB::collection('users')->where('name', 'John')->first();
+
+More examples
+-------------
+
 **Retrieving All Models**
 
     $users = User::all();
