+Open Closed loop in CLAMP
+-------------------------
+There is 2 closed loop levels in CLAMP:
+- Closed loop template: This is created from the DCAE blueprint (designed in the DCAE designer), and distributed by SDC to CLAMP.
+- Closed loop instance: Based on the template, it represents a physical closed loop in the platform related to a service and a VNF.
+	This is created in CLAMP when receiving the SDC notification, as this one is related to a specific service/vnf.
+
+There is no way to design a closed loop from scratch in CLAMP, you can only configure it and manage its life-cycle.
+For more info on how to design the service in SDC, check this: https://wiki.onap.org/display/DW/CLAMP+videos#CLAMPvideos-DesignpartinSDC
+
+There is a specific menu to open distributed closed loops in CLAMP UI. 
+
+|clamp-open-menu|
+
+Please note that the option "Create CL" can be used to create a closed loop from the template distributed by SDC, you can therefore instantiate it for another service/vnf 
+
+Once you click on "Open CL", this dialog box is shown
+
+|clamp-open-box|
+
+Once the distributed closed loop has been chosen, the closed loop is shown to the user
+
+|clamp-opened-closed-loop|
+
+Closed Loop properties
+----------------------
+You can check to which service/vnf the closed loop has been associated in SDC.
+
+|clamp-menu-prop|
+
+This opens a box that gives the properties set during the SDC notification deployment in CLAMP.
+Do not change those settings
+
+|clamp-prop-box|
+
+Operational policy properties
+-----------------------------
+The box "policy" is clickable, so the operational policies can be defined.
+By clicking on the button "New Policy", it's possible to add new operational policies that can chosen in the configuration policy. 
+
+|clamp-op-policy-box|
+
+Once clicked, it's possible to configure each operational policy that can also contain multiple "sub policies", one per Recipe
+
+|clamp-op-policy-box-policy1|
+
+Configuration policy properties
+-------------------------------
+The box "tca" is clickable, so the TCA configuration policy can be defined.
+In that popup dialog, multiple Thresholds can be defined, the operational policies defined previously can be chosen and set in the "Policy" field. 
+ 
+|clamp-config-policy-tca1|
+
+Saving Closed loop
+------------------
+Once all properties have been defined for all policies, the closed loop must be saved.
+
+|clamp-save-cl|
+
+Submitting the Closed loop to policy
+------------------------------------
+In the "Manage Menu", the submit action can be used to send the configuration to policy engine.
+The "Validation test" can be used to check the data configured in the closed loop without sending anything to policy engine.
+
+|clamp-submit-cl|
+
+If everything is successful, this changes the status to "Distributed" 
+
+|clamp-distributed|
+
+Deploy/undeploy the Closed loop to DCAE 
+---------------------------------------
+Once sent to policy engine, Clamp can ask to DCAE to deploy the micro service
+
+|clamp-deploy|
+
+This opens a window where the parameters of the DCAE micro service can be configured/tuned.
+The policy_id is automatically generated by Clamp in the previous steps.
+
+|clamp-deploy-params|
+
+Once deployed on DCAE the status Closed loop status goes to ACTIVE, it can then be Undeployed/Stopped or even Updated (this is to push new policies on policy engine)
