+## Service Mesh
+
+Ingress-perf is compatible with the OpenShift implementation of the Istio ingress-gateway, provided by OpenShift Service Mesh. To enable it it's necessary to pass the flag `--service-mesh=true`, when specified, `ingress-perf` will create its routes in the namespace specified by `--gw-ns`, by deault `istio-system`, these routes point to the http2 port of the `istio-ingress-gateway` service. 4 gateways and 1 virtualservice are also created in the `ingress-perf` namespace.
+
+At the time of writing these lines only the `http` and `edge` terminations are supported.
