 A La Carte mode Service Instantiation via ONAP SO API
 =====================================================
 
-Using ONAP SO API in "A La Carte" mode, you need to send several requests,
-depending on the service model composition.
+Using ONAP SO API in "A La Carte" mode, the user needs to send
+a request to instantiate the service object but also for each VNF/VF-module
+and network that compose the Service.
 
-For example, if your service model is composed of 2 VNF and a Network,
-you will have to build and send :
+ONAP will instantiate resources on Cloud platforms only when user is requesting
+to instantiate VF-module or Network (openstack neutron or contrail).
 
-* a request to SO to create the "service instance" object
-* a request to SO to create the VNF 1 instance object
-* a request to SDNC to declare VNF 1 instance parameters and values
-  (SDNC preload)
-* a request to SO to create the Vf-module 1 instance object
-* a request to SO to create the VNF 2 instance object
-* a request to SDNC to declare VNF 2 instance parameters and values
-  (SDNC preload)
-* a request to SO to create the Vf-module 2 instance object
-* a request to SO to create the Network instance object
+To instantiate a VF-module, it is required to have instantiated a VNF object.
+
+To instantiate a VNF object, it is required to have instantiated
+a Service object.
+
+To instantiate a Network object, it is required to have instantiated
+a Service object.

+**Requests**
+    * `Request to instantiate Service object`_
+    * `Request to instantiate VNF object`_
+    * `Requests to instantiate VF-module object`_
+    * `Requests to instantiate Neutron Network object`_
