-=== Spring @MatrixVariable Support
-
-Spring Cloud OpenFeign provides support for the Spring `@MatrixVariable` annotation.
-
-If a map is passed as the method argument, the `@MatrixVariable` path segment is created by joining key-value pairs from the map with a `=`.
-
-If a different object is passed, either the `name` provided in the `@MatrixVariable` annotation (if defined) or the annotated variable name is
-joined with the provided method argument using `=`.
-
-IMPORTANT:: Even though, on the server side, Spring does not require the users to name the path segment placeholder same as the matrix variable name, since it would be too ambiguous on the client side, Sprig Cloud OpenFeign requires that you add a path segment placeholder with a name matching either the `name` provided in the `@MatrixVariable` annotation (if defined) or the annotated variable name.
-
-For example:
-
-[source,java,indent=0]
----
-@GetMapping("/objects/links/{matrixVars}")
-Map<String, List<String>> getObjects(@MatrixVariable Map<String, List<String>> matrixVars);
----
-Note that both variable name and the path segment placeholder are called `matrixVars`.

----
-@FeignClient("demo")
-public interface DemoTemplate {
-
-    @GetMapping(path = "/stores")
-    CollectionModel<Store> getStores();
-}
----
-
-=== Feign `CollectionFormat` support
-We support `feign.CollectionFormat` by providing the `@CollectionFormat` annotation. You can annotate a Feign client method with it by passing the desired `feign.CollectionFormat` as annotation value.
-
-In the following example, the `CSV` format is used instead of the default `EXPLODED` to process the method.
-
-[source,java,indent=0]
----
-@FeignClient(name = "demo")
-	protected interface PageableFeignClient {
-
-		@CollectionFormat(feign.CollectionFormat.CSV)
-		@GetMapping(path = "/page")
-		ResponseEntity performRequest(Pageable page);
-
-	}
----
-
-TIP: Set the `CSV` format while sending `Pageable` as a query parameter in order for it to be encoded correctly.
-
-=== Reactive Support
-As the https://github.com/OpenFeign/feign[OpenFeign project] does not currently support reactive clients, such as https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/reactive/function/client/WebClient.html[Spring WebClient], neither does Spring Cloud OpenFeign. We will add support for it here as soon as it becomes available in the core project.
-
-Until that is done, we recommend using https://github.com/Playtika/feign-reactive[feign-reactive] for Spring WebClient support.
