+Implementation CRUD Sample
+==========================
+This sample demonstrates how new implementation types are constructed for 
+Apache Tuscany SCA. 
+
+The README in the samples directory (the directory above this) provides 
+general instructions about building and running samples. Take a look there 
+first. 
+
+If you want to try out the CRUD implementation type that this sample provides
+please see the implementation-crud sample that provides the necessary client
+code to bring up an application that uses this implementation extension.
+
+Sample Overview
+---------------
+This sample contains a CRUD implementation type as an example of how to create
+new implementation types. Components using this implementation type always
+expose the same Create, Retrieve, Update and Delete interface. This sample
+uses a singleton ResourceManager to perform the CRUD operations but of course
+a real component would provide a real implementation.

+Building The Sample Extension Using Ant
+-----------------------------------------
+With the binary distribution the sample extension can be built using Ant as 
+follows
+
+cd implementation-crud-extension
+ant compile
+
+See the implementation-crud sample to run a sample that uses this
+implementation extension.
+
+Building The Sample Using Maven 
+-------------------------------------------
+With either the binary or source distributions the sample can be built 
+using Maven as follows. 
+
+cd implementation-crud-extension
+mvn
+
+Maven will also test that the sample extension built properly. You should see 
+the following output from the test phase.
