+== This is a Developer Preview
+
+== Features
+
+* TODO: list features
+
+== Running the sample
+
+1. [Install consul](https://consul.io/downloads.html)
+2. Run `./run_consul.sh` found in the root of this project
+3. verify consul is running by visiting [http://localhost:8500](http://localhost:8500)
+4. run `mvn --settings .settings.xml package` this will bring in the required spring cloud maven repositories and build
+5. run `java -jar spring-cloud-consul-sample/target/spring-cloud-consul-sample-1.0.0.BUILD-SNAPSHOT.jar`
+6. visit [http://localhost:8080](http://localhost:8080), verify that `{"serviceId":"<yourhost>:8080","host":"<yourhost>","port":8080}` results
+7. run `java -jar spring-cloud-consul-sample/target/spring-cloud-consul-sample-1.0.0.BUILD-SNAPSHOT.jar --server.port=8081`
+8. visit [http://localhost:8080](http://localhost:8080) again, verify that `{"serviceId":"<yourhost>:8081","host":"<yourhost>","port":8081}` eventually shows up in the results in a round robbin fashion (may take a minute or so).

+This project provides Consul 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 Consul 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.
