+  description: >
+    Create a Cart. Although optional, specifying the cart's region and sales
+    channel can affect the cart's pricing and
+
+    the products that can be added to the cart respectively. So, make sure to
+    set those early on and change them if necessary, such as when the customer
+    changes their region.

+    If a customer is logged in, the cart's customer ID and email will
+    automatically be set.
