-There's an example inside the project, so you can test the code generation.
+To test with the Example provided, call the **test.sh** script (it will update the files inside the Example folder):

 You can call the CLI using the terminal, but you can also call it using Xcode. To do that, just edit the scheme and add **Arguments Passed On Launch**:
