 ### Creating orders in batch
 
 You can create up to 10 orders in batch.
 
+This updates all orders with a label_url and also gives you a labels_url with the combined labels
+
 ```ruby
-order1 = Smartsend::Order.new(...)
-order2 = Smartsend::Order.new(...)
 
-orders = Smartsend::Orders.new(order1, order2)
+orders = Smartsend::Orders.new
+orders << Smartsend::Order.new(...)
+orders << Smartsend::Order.new(...)
 
 # send the orders to Smartsend.io

+
 orders.first.label_url
-  => 'https://www.pacsoftonline.com/...'
+  => 'http://v70.api.smartsend.dk/...'
+```
+
+### Using multiple accounts
+
+If your system requires multiple accounts you can pass an account instance when saving orders.
+
+```ruby
+order = Smartsend::Order.new(...)
+
+account = Smartsend::Account.new(
+  email: 'smartsend-username',
+  license: 'smartsend-license-key'
+)
+
+order.save!(account: account)
