+Building Block based PNF PnP flows
+==================================
+
+.. image:: ../../images/proposed_building_blocks.png
+
+AssignPnfBB
+-----------
+
+* Responsibility:
+
+  * Creates PNF entry in AAI (with PNF name chosen by user)
+
+  * Additionally stores PNF model-related parameters in AAI:
+    * model-customization-id
+    * model-invariant-id
+    * model-version-id
+
+  * Makes a link in AAI between Service entry and PNF entry
+
+  * Sets PNF orchestration status in AAI to Assigned
+
+* Currently implemented in CreateAndActivatePnfResource.bpmn
+
+WaitForPnfReadyBB
+-----------------
+
+* Responsibility:
+
+  * Waits for "PNF ready" event sent from PRH to DMaaP
+    * pnfCorrelationId from the event must match PNF instance name provided by the user during service instantiation
+
+  * Sets PNF orchestration status in AAI to:
+    * Register - when starting to wait for PNF ready event
+    * Registered - when PNF ready event is successfully received
+
+  * Currently implemented in CreateAndActivatePnfResource.bpmn
+
+
+Support for config assign (ControllerExecutionBB, action: configAssign)
+-----------------------------------------------------------------------
+
+* Responsibility:
+  * Runs config assign via CDS
+
+* Currently implemented in ConfigurePnfResource.bpmn
+
+* We will reuse generic BPMN for calling CDS (ControllerExecutionBB)
+
+* Things to consider:
+  * SkipPostInstantiationConfiguration should be taken into account
+
+
+Support for config deploy (ControllerExecutionBB, action: configDeploy)
+-----------------------------------------------------------------------
+
+
+* Responsibility:
+  * Runs config deploy via CDS
+
+* Currently implemented in ConfigurePnfResource.bpmn
+
+* We will reuse generic BPMN for calling CDS (ControllerExecutionBB)
+
+* Things to consider:
+  * SkipPostInstantiationConfiguration should be taken into account
+
+ActivatePnfBB
+-------------
+
+* Responsibility:
+  * Sets PNF orchestration status in AAI as Active
+
+
+Sequence in Service-Macro-Create flow
+-------------------------------------
+
+1. AssignServiceInstanceBB
+2. CreateNetworkCollectionBB
+3. AssignNetworkBB
+4. AssignVnfBB
+5. AssignVolumeGroupBB
+6. AssignVfModuleBB
+7. **AssignPnfBB**
+8. **WaitForPnfReadyBB**
+9. **ControllerExecutionBB (action: configAssign, scope: pnf)**
+10. **ControllerExecutionBB (action: configDeploy, scope: pnf)**
+11. **ActivatePnfBB**
+12. ConfigAssignVnfBB
+13. CreateNetworkBB
+14. ActivateNetworkBB

+Legacy PNF PNP BPMN workflows
+=============================

+
+.. image:: ../../images/CreateAndActivatePnfResource.png
+
+* ConfigurePnfResource
+
+.. image:: ../../images/ConfigurePnfResource.png
+
+**Both included in CreateVcpeResCustService_simplified BPMN**
