+This python script is used to execute Traffic Distribution workflow on vFWDT service instance.
+It uses AAI, OOF and APPC API to perform steps necessary to distribute traffic from one to the other
+instance of vFW. Full description of the the use case can be found in here
+
+[ONAP vFW Traffic Distribution Use Case](https://docs.onap.org/en/latest/submodules/integration.git/docs/docs_vFWDT.html)
+
+Usage:
+
+`pip3 install -r requirements.txt --user`
+
+`python3 workflow.py 55f59a16-4c10-45e1-9873-6322a25d040a 10.12.5.63 True False False True`
+
+Input parameters:
+* vnf-id of vFW VNF instance that traffic should be migrated out from
+* IP of ONAP OOM Node (any)
+* if script should use and build OOF response cache
+* if instead of vFWDT service instance vFW or vFWCL one is used
+* if only configuration information will be collected
+* if APPC LCM action status should be verified and FAILURE should stop workflow
