-In this example we install the built-in `kubernetes` integration with the default built-in values, including the use of a user-created service account.
+In this example we define a `nginx` custom integration alongside a custom agent preset defined in [agent-nginx-values.yaml](agent-nginx-values.yaml) including the use of a user-created cluster role. Note that the user is responsible for assigning the correct permissions to the cluster role.
