GUI Text For Simple Game Tutorial

I’m pretty much new here and it’s been the second time I posted so far and I’ve been working my way around the resources provided here on Unity. However I looked into trying to display a block of text on the screen for game tutorial (ex. a FPS tutorial level where it pops up on the screen “Use W, A, S, D to walk” and such) for a certain amount of time then disappears. Can anyone point me towards a good direction?

  1. store time when showing starts
float startTime = Time.time;
  1. before to draw window with text, just check
if (Time.time < startTime + 5f)

this will show a window for 5 sec only
