Using pre/code:


```renpy

```

Demo:

init:

    # Set up the size of the screen, and the window title.
    $ config.screen_width = 800
    $ config.screen_height = 600
    $ config.window_title = "The Ren'Py Demo Game"

    # Declare the images that are used in the program.

typing up the script on the computer."

character's name next to the dialogue string."
