+## Example spec to use custom role
+
+CAPOCI can be used to create Subnet/NSG in the VCN for custom workloads such as private load balancers,
+dedicated subnet for DB connection etc. The roles for such custom subnest must be defined as `custom`.
+The following spec shows an example for this scenario.
