+Instantiate Service, VNF, VF modules and Network
+================================================
+
+
+Overview
+--------
+
+Using VID with A-La-Carte method means that the user needs to performed
+by himself the instantiation of each object  : service, VNF(s), VF module(s),
+network(s).
+
+ONAP to VIM interactions will occurs when instantiating/deleting VF module(s)
+or Network(s). In case of an Openstack VIM, Heat Stack(s) will
+be created/deleted.
+
+In the following description, the service model in SDC was composed of 1 VF
+and 1 Virtual Link (Generic Neutron Network)
+
+To be able to instantiate VF-module or Network object, some data need to be
+declared in ONAP SDNC using SDNC Rest API. It is the place where to put
+the instance specific values such as an IP address value specific
+to the VNF instance for example.
+
+In VID, terminologies are sometimes different than in other components:
+
+VNF in VID  = VF in SDC
+
+Node instance = VF in SDC
+
+Network = Virtual Link in SDC
+
+
+Pre-requisites
+--------------
+
+pre-instantiation operations must have been performed in AAI and VID,
+via Rest API, to declare some values for:
+
+- Subscriber Name (= customer in AAI)
+- Service Type or product family (= service subscription in AAI)
+- Project
+- Owning Entity
+- Line Of Business
+- Platform
+- LCP Region (= CloudOwner/RegionId in AAI)
+- Tenant
+
+see, in the ONAP User Guides, section about adding a CloudSite
+and section about pre-instantiation Operations
+
+
+Access to VID portal
+--------------------
+
+.. figure:: images/onap-portal.png
+   :align: center
+
+Select the VID icon
+
+.. figure:: images/vid-icon-on-portal.png
+   :align: center
+
+
+Here after, the VID Home page starts
+
+.. figure:: images/home.png
+   :align: center
+
+
+SDNC API selection
+------------------
+
+Select the API for "A-la-carte"
+
+There are two choices:
+
+- VNF_API (old) : VID will use the (old) "VNF" SDNC API
+  to get/check some parameters
+- GR_API (new) : VID will use the "Generic Resource"
+  SDNC API to get/check some parameters
+
+.. figure:: images/API_selection.png
+   :align: center
+
+
+
+Instantiate Service
+-------------------
+
+Click Browse SDC Service Models and search for the service to instantiate.
+
+The view show only service models in the DISTRIBUTED state.
+
+.. figure:: images/browse-service-models.png
+   :align: center
+
+
+Select a service and click Deploy.
+
+A dialog box displays.
+
+Complete the fields indicated by the red star and click Confirm.
+
+.. figure:: images/create-service-instance-alacarte.png
+   :align: center
+
+A status ox appears that shows the ONAP SO instantiation progress
+as well as any messages associated with the process.
+
+.. figure:: images/create-service-instance-alacarte-success.png
+   :align: center
+
+A Service object is created in ONAP.
+
+Click Close and next screen should appear.
+It will allow to declare VNF(s) and Network(s)
+that are part of the service model composition.
+
+.. figure:: images/create-service-instance-alacarte-VNF-network.png
+   :align: center
+
+
+Instantiate a VNF
+-----------------
+
+From previous screen, it is possible to declare a VNF: click on
+"Add node instance" and select the VNF you want to instantiate in the list
+
+The  following screen should appear:
+
+.. figure:: images/create-vnf-instance-alacarte.png
+   :align: center
+
+Complete the fields indicated by the red star and click Confirm.
+
+A VNF object will be declared in ONAP.
+
+Once, ONAP SO process is finished, click on close button.
+
+The following screen then should appear:
+
+
+.. figure:: images/create-service-instance-alacarte-after-vnf-instantiated.png
+   :align: center
+
+
+Warning: a this step, no VNF instance (e.g. VM) is created on the Cloud Platform.
+
+Click on "i" blue button to obtain VNF instance display information.
+
+From this screen, it will be possible to get:
+
+- the service instance id value
+- the VNF Type value
+
+Those information will be necessary for the "SDNC preload" step
+to instantiate the VF module
+
+Close that screen
+
+
+Instantiate VF Module
+---------------------
+
+It is now possible to declare a VF Module: click on
+"Add VF-Module" and select the VF-module you want to instantiate in the list
+
+The  following screen should appear:
+
+.. figure:: images/create-vfmodule-instance-alacarte.png
+   :align: center
+
+From this screen, it will be possible to get:
+
+- "Model Name" value
+
+At this step, with this "A-La-Carte" method, it is necessary to declare
+some information in ONAP SDNC.
+
+SDNC needs to be aware about the VNF before trying to use ONAP SO
+to instantiate the VF-module.
+
+This group of data is usually called "SDNC preload" and will contain:
+
+- vf-module instance Name
+- vnf instance Name
+- service instance id
+- the list of vnf parameters with values, when not using the default values
+
+Here is an example of SDNC preload for VNF, using "curl" tool
+to push those data using SDNC Rest API:
+
+::
+
+    curl -X POST \
+    http://sdnc.api.simpledemo.onap.org:30202/restconf/operations/VNF-API:preload-vnf-topology-operation \

+                    }
+                ],

+                }
+            }
+        }
+    }
+    '
+
+
+Data mapping between ONAP SDNC terminology and ONAP SO
+
+- "generic-vnf-name" value must be equal to the VNF instance name value
+  (see VNF instance detail screen)
+- "generic-vnf-type" value must be equal to VNF Type value
+  (see VNF instance detail screen)
+- "service-type" value must be equal to the service instance id value
+  (see VNF instance detail screen)
+- "vnf-name" value must be equal to the VF module instance name value
+- "vnf-type" value must be equal to the "Model Name" value
+  (see create VF module screen)
+
+
+If there is a need for an instance specific value
+of a VNF parameter (for example : an OAM network id value,
+specific to this VNF instance),
+the "vnf-parameters" must be completed with a list of name/value.
+
+Once the "SDNC preload" is completed, send it to SDNC using any Rest API Tool.
+
+Then, continue on VID and complete the fields indicated by the red star
+and click "Confirm".
+
+Warning : be very careful to use exactly the same VF module instance name
+on this screen and in the "SDNC preload"
+
+Wait for success and close the popup screen.
+
+The following screen should appear:
+
+.. figure:: images/create-service-instance-alacarte-after-vfmodule-instantiated.png
+   :align: center
+
+At that point, the VNF is now instantiated in the cloud platform.
+
+
+Instantiate Network
+-------------------
+
+Instantiating a network is quite similar to vf-module instantiation
+(there is also the need for a "SDNC preload")
+
+Click on "Add Network" and select the Network you want
+to instantiate in the list
+
+The  following screen should appear:
+
+.. figure:: images/create-network-instance-alacarte.png
+   :align: center
+
+
+Prepare the "SDNC preload" with:
+
+- "network-role": provide any value,
+- "network-technology": use "neutron" as this example will instantiate
+  a network using openstack neutron application
+- "service-type": value must be equal to "Service Name"
+  (=service model name) displayed on VID screen
+- "network-name": value must be equal to the desired network instance name,
+- "network-type": value must be equal to "Model Name""Generic NeutronNet"
+  displayed on VID screen
+
+In addition:
+
+- in "provider-network-information" section, it is possible to indicate
+  some network characteristics
+- it is possible to add a section about "subnets"
+
+Here after, an "SDNC preload" example that can be use for Network
+instantiation.

+
+Also, all those network information are available in ONAP AAI,
+under the terminology
+"l3-network", with the "neutron-network-id" and the "neutron-subnet-id"
+provided by
+the openstack platform.
+
+
+Deleting Network, VF module, VNF, Service
+-----------------------------------------
+
+To delete a service instance using VID, it is necessary to delete objects
+in the following sequence:
+
+- delete VF module(s)
+- delete VNF instance(s)
+- delete Network(s)
+- delete service instance
+
+To proceed those deletion, from VID Home screen
+
+- search for existing service instance
+- edit/view the service instance you want to delete
+- click on red button with white cross and confirm for each object
