+CLAMP <-> SDC
+~~~~~~~~~~~~~~
+
+The pairwise testing is executed against a default ONAP installation in the OOM.
+It briefly states the procedure to design an Automation Composition starting from service creation,
+adding the required ONAP component artifacts, policy and properties in the composition phase of SDC
+and finally distributing it to the CLAMP for Commissioning.
+SDC provides an interface for distributing the modeled services to the run time components.
+
+The instructions below will enable to design an Automation Composition. There are different phases to the design:
+
+Step 1: Design an automation composition template and associate it to a Service, the template represents the theoretical flow of the ACM.
+
+Step 2: Generate a deployment artifact that can be ingested by the Policy Framework
+
+Step 3: Distribute the automation composition to CLAMP, the csar is distributed to CLAMP over Dmaap
+
+Step 4: Policy Distribution will internally call Automation Composition Commissioning rest endpoint
+
+Step 5: Service Template is commissioned in CLAMP, and can be followed by Instantiation and state changes.
+
+General Setup
+*************
+
+The kubernetes installation allocated all policy components across multiple worker node VMs.
+The worker VM hosting the policy components has the following spec:
+
+- 16GB RAM
+- 8 VCPU
+- 160GB Ephemeral Disk
+
+The ONAP components used during the pairwise tests are:
+
+- CLAMP automation composition runtime, policy participant, kubernetes participant.
+- SDC for running SDC components.
+- DMaaP for the communication between Automation Composition runtime and participants.
+- Policy Framework components for instantiation and commissioning of automation compositions.
+
+Testing procedure
+*****************
+
+The test set focused on the following use cases:
+
+- Design of participants and automation composition elements
+- Design of Automation Composition template including the above designed participants and automation composition element templates.
+- Distribution of designed template along with other artifacts as a csar to policy-distribution
+- Commissioning of template in automation composition runtime.
+
+Configuration changes
+*********************
+
+Following are certain configuration changes required/cross-checked
+1. policy-distribution configuration should include toscaAutomationCompositionDecoderConfiguration
+   File: kubernetes/policy/components/policy-distribution/resources/config/config.json
+
+   - Automation composition decoders and forwards should be present. Reference: `Sample Configuration <json/pd_config.json>`
+
+Design of participants and automation composition elements:
+----------------------------------------------------------
+Different participants and automation composition elements are created in SDC dashboard with the models available for automation composition.
+
+SDC provides a graphical interface for onboarding/designing resources (such as VNFs, PNFs, CNFs) and designing services composed of such resources
+
+- Create as many participants as needed to present in the automation composition
+- Select VF, provide name of the participant. Choose Model as AUTOMATION COMPOSTIION and Category as Participant.

+  .. image:: images/sdc_create_participant.png
+
+- Create as many automation composition elements as needed to present in the automation composition
+- Select VF, provide name of the automation composition element. Choose Model as AUTOMATION COMPOSTIION and Category as AutomationComposition Element.
+
+  .. image:: images/sdc_create_element.png
+
+- Add properties as required for an automation composition element
+- Add any properties where input is needed in Inputs tab.
+
+  .. image:: images/sdc_element_props.png
+
+- Create an automation composition
+- Select Service, provide name of the automation composition. Choose Model as AUTOMATION COMPOSTIION and Category as AutomationComposition.
+
+  .. image:: images/sdc_create_acm.png
+
+- SDC Composition tab
+- Drag and Drop the previously created participants and automation composition elements into the Compistion pane.
+- Drag and Drop the policies that needs to be added to the service template.
+
+  .. image:: images/sdc_compose_acm.png
+
+- For a pre validation, Tosca artifacts can be downloaded and verified
+
+  .. image:: images/sdc_tosca.png
+
+- From SDC dashboard, perform a distribution of the automation composition
+
+  .. image:: images/sdc_distribute.png
+
+- An Automation Composition is created by commissioning a Tosca template with Automation Composition definitions.
+This commissioned tosca service template can be further used from Policy-GUI for instantiating the Automation Composition with the state "UNINITIALISED".
+
+- Instantiate the commissioned Automation Composition definitions from the Policy Gui under 'Instantiation Management'.
+
+  .. image:: images/create-instance.png
+
+-  Verification: The automation composition is created with default state "UNINITIALISED" without errors.
