+This project provides a library for building an API Gateway on top of Spring MVC. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency.
+
+## Features
+
+Spring Cloud Gateway features:
+
+* Built on Spring Framework 5, Project Reactor and Spring Boot 2.0
+* Able to match routes on any request attribute.
+* Predicates and filters are specific to routes.
+* Hystrix Circuit Breaker integration.
+* Spring Cloud DiscoveryClient integration
+* Easy to write Predicates and Filters
+* Request Rate Limiting
+* Path Rewriting
+
+## Getting Started
+
+```java
+@SpringBootApplication
+public class DemogatewayApplication {
+	@Bean
+	public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
+		return builder.routes()
+			.route("path_route", r -> r.path("/get")
+				.uri("http://httpbin.org"))
+			.route("host_route", r -> r.host("*.myhost.org")
+				.uri("http://httpbin.org"))
+			.route("rewrite_route", r -> r.host("*.rewrite.org")
+				.filters(f -> f.rewritePath("/foo/(?<segment>.*)", "/${segment}"))
+				.uri("http://httpbin.org"))
+			.route("hystrix_route", r -> r.host("*.hystrix.org")
+				.filters(f -> f.hystrix(c -> c.setName("slowcmd")))
+				.uri("http://httpbin.org"))
+			.route("hystrix_fallback_route", r -> r.host("*.hystrixfallback.org")
+				.filters(f -> f.hystrix(c -> c.setName("slowcmd").setFallbackUri("forward:/hystrixfallback")))
+				.uri("http://httpbin.org"))
+			.route("limit_route", r -> r
+				.host("*.limited.org").and().path("/anything/**")
+				.filters(f -> f.requestRateLimiter(c -> c.setRateLimiter(redisRateLimiter())))
+				.uri("http://httpbin.org"))
+			.build();
+	}
+}
+```

+To run your own gateway use the `spring-cloud-starter-gateway` dependency.
