 # Common ReST Client Library
 
-This project provides a library for Spring and POJO-based REST client instantiation.  It includes special classes with classifiers for two popular JAXRS-based client frameworks: Apache CXF and Jersey.

 #### Multiple Clients
 
 If you will or may have multiple clients in your Spring context, there is an extra step.  You will still need to define a `ClientConfiguration` for each.  On top of that, you will need to create specialized implementations of each client.  That special implementation will reference the configuration directly.  An example is below.
 
 ```java
 @Component("my.client")
-public class MyClient extends ClientCxfImpl {
