 The tool will prompt you for:
 
-- Name of the controller. If the name had been supplied from the command line, the prompt is skipped and the controller is built with the name from the command-line argument.

+If you select the Empty Controller, it will generate a nearly-empty template
+based on the given name:
 
-The tool will create a new file as <code>/src/controllers/<i>controller-name</i>.controller.ts</code>. The file will contain an empty constructor and common package imports that can be uncommented.

+If you select the REST Controller with CRUD Methods type, you will then be asked
