+## Batch-creating EMPI Links
+
+The `$empi-batch-run` operation is used to batch-process patients and practitioners. In normal operation, an interceptor will 
+run EMPI processing over Resources when they are updated or created, but this is not the only context in which you would want to 
+execute EMPI processing against resources. In the rules-tuning phase of your setup, you may use `$empi-batch-run` to quickly apply EMPI rules across multiple Resources.
+
+After the operation is complete, all targeted EMPI links will be removed from the system, and the Person resources which were involves in those links will be deleted and expunged 
+from the server. 
+
+This operation takes a single optional Parameter.
