[Q] Aroma Installer

Hi guys,

I'm trying to set up Aroma Installer for my own Custom ROM. When I try to flash the ROM, it shows all but when i had nearly finished it let me choose Installation Demo and other options. This will flash the ROM or it will show me what will happen without flashing it?

If it is only a demostration, what I have to do to flash the ROM definetly?

Thank you!!!
