Kiali provides a dashboard to

Once the ServiceMeshControlPlane has been created, guide users to access the Kiali web console to validate the status of the Control Plane components.

In the book info installation example, add a step to verify the installation with Kiali. Consider adding a screenshot of the deployed application.

When enabling side car injection, add steps to verify that the proxies have successfully been added using Kiali. Point out that proxy logs and Proxy configuration can be accessed via kiali. There is a separate issue to provide instructions on kiali logs: https://issues.redhat.com/browse/OSSMDOC-337, thus don't need to reproduce here. Explain that proxy configuration is managed by the control plane, though it can be viewed via Kiali for debugging/validation purposes. Kiali also provides some explanation of the log values (some of this content could go in the troubleshooting section, but we should mention this here).

In the security section, add steps to validate that traffic is encrypted via Kiali (and/or Grafana if necessary).

In traffic management, add steps to validate Istio resources using Kiali (this can probably be broken down more - may be an epic on its own).
