 A central concept in Spring Cloud's Feign support is that of the named client. Each feign client is part of an ensemble of components that work together to contact a remote server on demand, and the ensemble has a name that you give it as an application developer using the `@FeignClient` annotation. Spring Cloud creates a new ensemble as an
 `ApplicationContext` on demand for each named client using `FeignClientsConfiguration`. This contains (amongst other things) an `feign.Decoder`, a `feign.Encoder`, and a `feign.Contract`.
+It is possible to override the name of that ensemble by using the `contextId`
+attribute of the `@FeignClient` annotation.

+=== Feign @QueryMap support
+
+The OpenFeign `@QueryMap` annotation provides support for POJOs to be used as
+GET parameter maps. Unfortunately, the default OpenFeign QueryMap annotation is
+incompatible with Spring because it lacks a `value` property.
+
+Spring Cloud OpenFeign provides an equivalent `@SpringQueryMap` annotation, which
+is used to annotate a POJO or Map parameter as a query parameter map.
+
+For example, the `Params` class defines parameters `param1` and `param2`:
+
+[source,java,indent=0]
+----
+// Params.java
+public class Params {
+    private String param1;
+    private String param2;
+
+    // [Getters and setters omitted for brevity]
+}
+----
+
+The following feign client uses the `Params` class by using the `@SpringQueryMap` annotation:
+
+[source,java,indent=0]
+----
+@FeignClient("demo")
+public interface DemoTemplate {
+
+    @GetMapping(path = "/demo")
+    String demoEndpoint(@SpringQueryMap Params params);
+}
+----
+
+If you need more control over the generated query parameter map, you can implement a custom `QueryMapEncoder` bean.
+
+=== HATEOAS support
+
+Spring provides some APIs to create REST representations that follow the https://en.wikipedia.org/wiki/HATEOAS[HATEOAS] principle, https://spring.io/projects/spring-hateoas[Spring Hateoas] and https://spring.io/projects/spring-data-rest[Spring Data REST].
+
+If your project use the `org.springframework.boot:spring-boot-starter-hateoas` starter
+or the `org.springframework.boot:spring-boot-starter-data-rest` starter, Feign HATEOAS support is enabled by default.
+
+When HATEOAS support is enabled, Feign clients are allowed to serialize
+and deserialize HATEOAS representation models: https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/EntityModel.html[EntityModel], https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/CollectionModel.html[CollectionModel] and https://docs.spring.io/spring-hateoas/docs/1.0.0.M1/apidocs/org/springframework/hateoas/PagedModel.html[PagedModel].
