+This project provides Zookeeper integrations for Spring Boot apps through autoconfiguration
+and binding to the Spring Environment and other Spring programming model idioms. With a few
+simple annotations you can quickly enable and configure the common patterns inside your
+application and build large distributed systems with Zookeeper based components. The
+patterns provided include Service Discovery, Circuit Breaker and Configuration.
+Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon) are provided by
+integration with Spring Cloud Netflix.
