+# About Spring Cloud and Java Chassis interoperability
+
+In this demo, we build a gateway using spring-cloud-gateway, a microservice `provider-java-chassis` using Java Chassis, a microservice `provider-spring-cloud` using Spring Cloud. 
+
+Scenario 1:  User -> gateway -> provider-spring-cloud -> provider-java-chassis
+
+Request:
+
+    `http://localhost:9090/spring-cloud/sayHello?name=World`
+
+Result:
+
+    `"Hello from Java Chassis, World"`
+
+
+Scenario 2:  User -> gateway -> provider-java-chassis -> provider-spring-cloud
+
+Request:
+
+    `http://localhost:9090/java-chassis/sayHello?name=World`
+
+Result:
+
+    `"Hello from Spring Cloud, World"`
+
+## Using Service Center & Kie
+
+Maven profile and Spring Profile using `servicecomb`. 
+
+## Using Nacos
+
+Maven profile and Spring Profile using `nacos`.
+
+>>> Notice: Nacos 2.3.0 and above is required. Because older versions of nacos will not generate instance id for Spring Cloud applications and Java Chassis interoperability needs instance id.
