Typekit for Books

I'm trying to add a font using Typekit.  My goal is to add a font to use in Adobe InDesign to create a published and printed hardcover book.  However, Typekit requires me to add the font to my kit - and the kit requires me to supply a domain name -- which indicates that I'm setting this up for a website, not a book!

I must be missing something here.  Can anyone point me in the right direction how to add a font to InDesign?  The one in particular is called Lint McCree.

Many thanks!
