-## Update Cart
+## Updating Multiple Items In Your Cart
 
 When viewing your cart, it's currently not possible to update all your line items at once - instead it must be done for each line item as a separate event. This controller let's you update multiple line items at once.  This might be desirable when a user has multiple line items in their cart, and wants to update quantities all at once by clicking an 'Update Cart' button.

+## Twig Tags
+
+MultiAdd also provides a few extra useful twig tags that you can use to perform cart operations directly in your templates.
+
+Example - Setup:
+
+```
+{% set cart = craft.commerce.cart %}
+{% set items = [] %}
+
+{% set items = items|merge([{"purchasableId":1385,"qty":1, "note":"Test note"}]) %}
+{% set items = items|merge([{"purchasableId":854,"qty":2, "options": {"colour":"green"} }]) %}
+```
+
+Items is an array, and now holds:
+
+```
+array(2) {
+  [0]=>
+  array(3) {
+    ["purchasableId"]=>
+    int(1385)
+    ["qty"]=>
+    int(1)
+    ["note"]=>
+    string(9) "Test note"
+  }
+  [1]=>
+  array(3) {
+    ["purchasableId"]=>
+    int(854)
+    ["qty"]=>
+    int(2)
+    ["options"]=>
+    array(1) {
+      ["colour"]=>
+      string(9) "green"
+    }
+  }
+}
+```
+
+Example Twig Operations:
+
+```
+# add items to cart
+{{ craft.multiAdd.multiAddToCart(cart, items) }}
+
+# remove the first line item
+{{ craft.multiAdd.removeLineItem(cart, cart.lineItems[0].id ) }}
+
+# clear the cart
+{{ craft.multiAdd.removeAllLineItems(cart) }}
+```
