The document describes the steps that can be used to create and onboard optimization policies for the Network Slice and Subnet models onto the Policy module in ONAP. These policies will be used by OOF during the optimization(NSI and NSSI selection).

Prerequisites
Make sure that the policy and OOF modules are deployed and all the pods are up and running. You can check the pod status using the following command
...
- policy_types (dir) - The directory contains the addtional policy types that needs to be created for the Network slicing use case.
- nst_policies (dir) - The directory contains the policies required for NST selection.
- nsi_polices (dir) - The directory contains the policy templates required for NSI selection.
- nssi_policies (dir) - The directory contains the policy templates required for NSSI selection.
- policy_utils.py - The python script which can be used to generate, create and delete policies
