-## Spring Cloud Config ##
-
-To get this example working, you have to initialize a new *Git* repository in
-the ```client-config``` directory first *and* you have to set the environment variable
-```CONFIG_REPO``` to an absolute path of that directory.
-
-```
-$> cd client-config
-$> git init
-$> git add .
-$> git commit -m 'Initial commit'
-$> export CONFIG_REPO=$(pwd)
-```
-
-Then you're able to run the examples with ```mvn install spring-boot:run```.
-
-### Docker ###
-
-To get the *Docker* examples working, you have to repackage the ```spring-cloud-config-server```
-and ```spring-cloud-config-client``` modules first:
-
-```
-$> mvn install spring-boot:repackage
-```
-
-Don't forget to download the *Java JCE* package from
-(Oracle)[http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html].
