 # tfmod-kiali
 
+Kiali is a web console for the Istio Service Mesh. It is analogous to how the Kubernetes Dashboard is a web console for Kubernetes, ie. it is a web interface for viewing configurations and operations of the system. Additionally, the same as the Kubernetes Dashboard, we deploy Kiali in a read-only manner, given mesh objects should only be configured through code and pipelines, not modification through web or command line. Kiali provides a useful tool for reviewing configurations and topology, observing mesh health and performance, and tracing along with its associated details. Additional details about Kiali can be reviewed at the [Kiali website](https://kiali.io/).
+
+This module deploys and configures Kiali via its operator and integrates it with Istio and the other telemetry oriented tools of the cluster.
