 The structure of the code is very similar to the previous examples.  Setup the client, setup the call, perform the call.  Every request follows this same pattern.

+Creating a New Release
+----------------------
+
+Update the version of the SDK before creating a new release. The format is `<major>.<minor>.<patch>`, where the 
+`<major>.<minor>` numbers must match the version of BP. The `<patch>` is an incrementing number that increments with 
+each SDK release for a given major/minor release.
+
+The version is specified in `CMakeLists.txt`.
