Enable/start dialog?

How can I make my dialogue show up in game? There are two ways of doing this: you can use GDScript or the Scene Editor.

Using the Dialogic class, you can add dialog nodes from code easily:

var new_dialog = Dialogic.start('Your Timeline Name Here')
add_child(new_dialog)

Using the editor, you can drag and drop the scene located at /addons/dialogic/Dialog.tscn and set the current timeline via the Inspector.
