 The _src/test/java/org/hyperledger/fabric/sdkintegration/End2endIT.java_ integration test is an example of installing, instantiating, invoking and querying a chaincode.
 It constructs the Hyperledger channel, deploys the `GO` chaincode, invokes the chaincode to do a transfer amount operation and queries the resulting blockchain world state.
 
+The _src/test/java/org/hyperledger/fabric/sdkintegration/End2endAndBackAgainIT.java_  Shows recreating the channel objects created in End2endIT.java and
+upgrading chaincode and invoking the up graded chaincode.
+
+Between End2endIT.java and End2endAndBackAgainIT.java this code shows almost all that the SDK can do.
+ To learn the SDK you must have some understanding first of the Fabric. Then  it's best to study these two integrations tests  and better yet work with them in a debugger to follow the code. ( *a live demo* )
+ Then once you understand them you can cut and paste from there to your own application. ( _the code is done for you!_ )
+
+
 This test is a reworked version of the Fabric [e2e_cli example](https://github.com/hyperledger/fabric/tree/master/examples/e2e_cli) to demonstrate the features of the SDK.
 To better understand blockchain and Fabric concepts, we recommend you install and run the _e2e_cli_ example.
