Adding Help Text to Newly Created Functions

I am creating a few new functions that are to be visible in the Fx area.
Ordinarily, when I choose a worksheet function, I can get help on that, and
there is text associated with how to use the function in the dialog box. How
do I do that?

My approach has been to insert a Module, code a function:

Public Function HelloWorld(x as string) as string

HelloWorld="Try something more important, " + x

End Function

So, what do I have to add here to get additional information to show up in
the function dialog box?
