 ## response
 Unlike other *provider_type*s `response` does not automatically receive data from a source. Instead a `response` provider is available to be a "sink" for data originating from an HTTP response. The `response` provider has the following parameters.
 
 - **`auto_return`** <sub><sup>*Optional*</sup></sub> - This parameter specifies that when this provider is used and an individual endpoint call concludes, the value it got from this provider should be sent back to the provider. Valid options for this parameter are `block`, `force`, and `if_not_full`. See the `send` parameter under the [endpoints.provides subsection](./endpoints-section.md#provides-subsection) for details on the effect of these options.
 - **`buffer`** <sub><sup>*Optional*</sup></sub> - Specifies the soft limit for a provider's buffer. This can be indicated with an integer greater than zero or the value `auto`. The value `auto` indicates that if the provider's buffer becomes empty it will automatically increase the buffer size to help prevent the provider from becoming empty again in the future. Defaults to `auto`.
 - **`unique`** - <sub><sup>*Optional*</sup></sub> A boolean value which when `true` makes the provider a "unique" provider--meaning each item within the provider will be a unique JSON value without duplicates. Defaults to `false`.
 
+**Example**, the following:
+```yaml
+providers:
+  - session:
+    - response:
+        buffer: 1000
+        auto_return: if_not_full

 ## list
 The `list` *provider_type* creates a means of specifying an array of static values to be used as a provider.
 A `list` provider can be specified in two forms, either implicitly or explicitly. The explicit form has the following parameters:
