         There are two ways to do a refund:
-        * refund a specific amount which is divided across all the line items.
-        * refund quantities of line items.
-        If you want to refund the entire refundable amount on the invoice, the
-        simplest way is to do `type=amount` without specifiying an `amount`.
+        * Apply a specific dollar/cent amount or percentage amount to an entire invoice, which will refund the resulting amount across all line items on the invoice.
+          * If you want to refund the entire refundable amount on the invoice, the simplest way is to do `type=amount` without specifiying an `amount`.
+          * Note: You must have the Credit Memos feature flag enabled on your site to utilize percentage amount refunds on invoices.
+        * Apply a refund to one or more individual line items on an invoice. A line item can be refunded by a quantity amount, a specific dollar/cent amount, or a percentage amount and will only apply to the specific line item you are aiming to refund.
