Best method for showing text1, then clicking to move onto text2

I want an intro for my game where some text fades in, then the user clicks to fade the text out, and fade the next bit in. I can code all this manually of course, but is there a quick and easy method (a simple reusable function etc) to make this process easier?

One word Tweening.

Here are two free plugins you can use for any lerping:

ITween
LeanTween
