+************
+Installation
+************
+
+Currently, we use the Jaeger tracing all-in-one Kubernetes template for development and testing,
+which uses in-memory storage. It can be deployed to the istio-system namespace with the
+following command::
+
+ kubectl apply -n istio-system -f https://raw.githubusercontent.com/jaegertracing/jaeger-kubernetes/master/all-in-one/jaeger-all-in-one-template.yml
+
+The standard Jaeger REST port is at 16686. To make this service available outside of the
+Kubernetes cluster, use the following command::
+
+ kubectl expose -n istio-system deployment jaeger-deployment --port=16686 --type=NodePort
+
+Kubernetes will expose the Jaeger service on another port, which can be found with::
+
+ kubectl get svc -n istio-system
+
+An example listing from the command above is shown below where the Jaeger service is exposed
+externally on port 30888::
+
+ istio-system jaeger-deployment NodePort 10.104.113.94 <none> 16686:30888/TCP
+
+Jaeger will be accessible using the host IP of the Kubernetes cluster and port provided.

+Validate
+********
+
+The script in ``clover/tracing`` validates Jaeger installation::
+
+ python clover/tracing/validate.py
+
+It validates the installation with the following criteria:
+
+#. Existence of Jaeger all-in-one deployment using Kubernetes
+#. Jaeger service is accessible using IP address and port configured in installation steps
+#. Jaeger can retrieve default service listing for default Istio components
+#. TBD - consider installation of production setup with cassandra or elastic search
