How does my audience know to which number they need to send their vote and with which keyword the message needs to start?

At the moment you press on ‘Start free session’ or ‘Start credit session’ and you enter your activation code the footers in the questionslide/resultslide will change automatically into an explanation for your audience. In the explanation it says to which number they need to send their message and with which (key)word they need to start their message.
