It’s major aim is to lower the barrier to entry to this new medium – on the go digital art. This is a help-along website with links to scary world of manuals/Youtube but presented calmly without fanfare. If you’ve not ordered your book, you can buy it on Amazon or anywhere else books are sold (Amazon Link)
The words Key I, Key II follow the book’s index and stand for chapters Key I, Key II in the book.
