Use Environment for defaulting app name and port

README.md

+Ths project provides Netflix OSS integrations for Spring Boot apps through autoconfiguration
+and binding to the Spring Environment and other Spring programming model idioms.
+
+# Eureka Clients
+
+Example eureka client:
+
+```
+@Configuration
+@ComponentScan
+@EnableAutoConfiguration
+@RestController
+public class Application {
+
+	@RequestMapping("/")
+	public String home() {
+		return "Hello world";
+	}
+	
+	public static void main(String[] args) {
+		new SpringApplicationBuilder(Application.class).web(true).run(args);
+	}
+
+}
+
+```
+
+(i.e. utterly normal Spring Boot app). Configuration is required to locate the Eureka server. Example:
+
+```
+eureka:
+  client:
+    serviceUrl:
+      defaultZone: http://localhost:8080/v2/
+      default.defaultZone: http://localhost:8080/v2/
+```
+
+The default application name, virtual host and non-secure port are taken from the `Environment` is 
+`${spring.application.name}`, `${spring.application.name}.mydomain.net` and `${server.port}` respectively.
