+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.
+
+implementation-crud-extension/
+ src/
+ main/
+ java/
+ crud/ - implementation model interfaces
+ backend/ - fake component implementation
+ impl/ - implementations of the model interfaces
+ provider/ - runtime implementation
+ resources/
+ META-INF/
+ services/ - declares the extension
+ test/
+ java/
+ crud/
+ CRUDTestCase.java - JUnit test case
+ resources/
+ crud.composite - the SCA assembly used during unit testing
+
+ build.xml - the Ant build file
+ pom.xml - the Maven build file
+
+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.
