How do you specify the post-launch html

In the documentation I see this example reference
[tminus t=”2012-12-20″ launchtarget=”below”/]
The area that the post-launch HTML is to be displayed in
(above, below, countdown or countup – default is ‘countdown’)

But it’s not explained very well, how do I define the post-launch HTML?
