 An end-to-end example that creates an event streams instance with key protect.
 This example uses the IBM Cloud terraform provider to:
  - Create a new resource group if one is not passed in.
  - Create a Key Protect instance and root key in the provided region.
- - Create a new event streams instance in the resource group and region provided, encrypted with the root key created above, and configured with topics and schemas.
+ - Create a new event streams instance in the resource group and region provided along with configured topics and schemas.
