+## Spring Cloud Launcher
+
+### Building
+
+`./mvnw clean install` from parent directory
+
+### Installing
+
+Install Spring CLI first: https://github.com/spring-cloud/spring-cloud-cli/blob/master/docs/src/main/asciidoc/install.adoc
+
+```
+$ spring install org.springframework.cloud:spring-cloud-cli:1.2.0.BUILD-SNAPSHOT
+```
+
+### Running
+
+```
+$ spring cloud
+```
+
+Currently starts configserver, eureka, h2 (db server), hystrixdashboard and kafka. [Here](https://github.com/spring-cloud/spring-cloud-cli/blob/devtools/spring-cloud-launcher/spring-cloud-launcher-deployer/src/main/resources/cloud.yml) is the full configuration.
+
+### Configuring
+
+Spring Cloud Launcher use normal Spring Boot configuration mechanisms. The config name is `cloud`, so configuration can go in `cloud.yml` or `cloud.properties`.
+
+For example, to run configserver and eureka, create a `cloud.yml` that looks like:
+```
+spring:
+  cloud:
+    launcher:
+      deployables:
+        - name: configserver
+          coordinates: maven://org.springframework.cloud.launcher:spring-cloud-launcher-configserver:1.1.0.BUILD-SNAPSHOT
+          port: 8888
+          waitUntilStarted: true
+          order: -10
+        - name: eureka
+          coordinates: maven://org.springframework.cloud.launcher:spring-cloud-launcher-eureka:1.1.0.BUILD-SNAPSHOT
+          port: 8761
+```
+
+The `name` attribute is required. If `waitUntilStarted` is true, Launcher will block until the application has reached the `deployed` state. Before commands are deployed, the list is sorted using Spring's `OrderComparator`. In the above case, `configserver` is deployed before any other app is deployed. Currently only `maven:` coordinates and standard Spring Resources (`file:`, etc...) are supported. 
+
+You can also use the `--deploy` option to select from the [predefined deployables](https://github.com/spring-cloud/spring-cloud-cli/blob/devtools/spring-cloud-launcher/spring-cloud-launcher-deployer/src/main/resources/cloud.yml). For example to run Spring Cloud Data Flow execute:
+```
+spring cloud --launch=configserver,h2,kafka,dataflow
+```
+
+### Stopping
+
+`Ctrl-C` in the same terminal `spring cloud` was run.
