How do I make certain words pop up on screen at a certain time?

I know this is probably one of the most easiest questions, but I'm VERY NEW to scripting and I know what type of game I'm going to make but I really need to learn how to do this to start it off. Thank you so much! :) Sorry I don't know what some of the tags mean, but I did my best.

Create a message or hint, wait a few seconds, and then remove it. See this page: http://wiki.roblox.com/index.php?title=How_to_Utilize_ROBLOX_Messages

you can do this by inserting an admin command script.

Not quite sure what you mean by this, And im new to scripting aswell but I have an idea of what is needed for it to work im just not entirely sure how to script it. But...

You'll need a timer, a set of words and the print function..

m=Instance.new("Message")--Change to hint if you want the banner at the top of the screen.
m.Parent=game.Workspace
m.Text="What ever text you want"
wait(3)--How long you want it too appear
m:Destroy()

Then you can use an event to determine when it pops up.
