+User output
++++++++++++
 
-* ``UserInput(non_interactive)``: class to manage user inputs. In this example we're using ``ui.request_boolean("Do you want to proceed?")``,
-  so it'll be automatically translated to ``Do you want to proceed? (yes/no):`` in the command prompt.
-  **Note**: you can use ``UserInput(non_interactive=conan_api.config.get("core:non_interactive"))`` too.
-* ``ConanOutput()``: class to manage user outputs. In this example, we're using only ``out.writeln(message, fg=None, bg=None)``
-  where ``fg`` is the font foreground, and ``bg`` is the font background. Apart from that, you have some predefined methods
-  like ``out.info()``, ``out.success()``, ``out.error()``, etc.
