Make sure player read instruction then proceed to next scene

Normally games will have instruction to teach players how to play the games. In order to make sure that the player have read the instruction before proceeding. I have a guiText which player have to click to proceed. So what i want to do is to like set a period of time then make the guiText appear on the scene? I know i need to create a timer to set when i want the guiText to appear.

Invoke and coroutines are going to be your best friends.

what i would do is either have a yield WaitForSeconds(5);
next one is enabled and other one is disabled, then another yield

or a simple touch motion so after the player has read it he touches the gui and then the next one comes up, or both depending on what u need.
