Hi-ReS! Stats

Need help on how to apply Hi-ReS! Stats to a Stencyl game.
I found some instructions that says:-

import net.hires.debug.*;
addChild( new Stats() );
By using Flash Builder, you can enable the Stats object:
CONFIG::DEBUG
{
    import net.hires.debug.*;
    addChild( new Stats() );

I'm not very technical, so I don't understand where you actually put all this code in your game, say for example the sample game DropBlock.

Much appreciated.
