 This example demonstrates how to use Go kit to implement a REST-y HTTP service.
 It leverages the excellent [gorilla mux package](https://github.com/gorilla/mux) for routing.
+
+Run the example with the optional port address for the service: 
+
+```bash
+$ go run ./cmd/profilesvc/main.go -http.addr :8080
+ts=2018-05-01T16:13:12.849086255Z caller=main.go:47 transport=HTTP addr=:8080
+```
+
+Create a Profile:
+
+```bash
+$ curl -d '{"id":"1234","Name":"Go Kit"}' -H "Content-Type: application/json" -X POST http://localhost:8080/profiles/
+{}
+```
+
+Get the profile you just created
+
+```bash
+$ curl localhost:8080/profiles/1234
+{"profile":{"id":"1234","name":"Go Kit"}}
+```
