+ *     .withResultOutputTag(results));
+ * }</pre>
+ *
+ * <p>As a client, you need to provide at least the following things:
+ *
+ * <ul>
+ *   <li>retry configuration
+ *   <li>need to specify AwsClientsProvider. You can pass on the default one BasisDynamodbProvider
+ *   <li>an output tag where you can get results. Example in DynamodbIOTest
+ * </ul>

 Review comment:
   nit: Rename to `DynamoDBIO` and use always the casing of the product name (save if it is for conventions reasons like package names), otherwise always the same casing that the data store, e.g. in comments too.
