Changing the default text for various pages with Modern UI

Hi,
I hope I won't be cursed for such an easy question as this. I thought it to be easy, but when I got to it, I am stumbled.

How would I change the text for, say, "welcome" page with Modern UI? For example, I'd like it to say "welcome to my wizard. Sit back and drink cup of coffee while I install this for you 🙂".I tried to add Text="..." to the "label" fields in iospeal.ini, but that did not seem to produce any visible results.
Is creation of custom pages the only way out? Also, the documentation mentions the iowizard.ini, but I can't find it anywhere in ${NSISDIR}. I am running 2.0 Beta 3.

I'd appreciate any help.

Please read the docs (language files).

Example:

!define MUI_TEXT_WELCOME_INFO_TEXT "You are about to install a very cool application.\r\n\r\n"



!insertmacro MUI_LANGUAGE "English"

You can modify ioSpecial.ini (fixed the documentation error) to modify the layout, not the texts.

Quick thanks for your help.
