 By calling :method:`Symfony\\Component\\Console\\Tester\\CommandTester::setInputs`,
 you imitate what the console would do internally with all user input through the CLI.
+This method takes an array as only argument with, for each input that the command expects,
+a string representing what the user would have type.
 This way you can test any user interaction (even complex ones) by passing the appropriate inputs.
+
+.. note::
+    The :class:`Symfony\Component\Console\Tester\CommandTester` automatically simulates a user hitting
+    ``ENTER`` after each input, no need for passing an additional input.
