-If the document does not already exist, the contents of the `upsert` element
-are inserted as a new document. If the document exists, the
-`script` is executed:
+An upsert operation lets you update an existing document or insert a new one if it doesn't exist, in a single request.
+
+In this example, if the product with ID `1` exists, its price will be updated to `100`. If the product does not exist, a new document with ID `1` and a price of `50` will be inserted.
