Piezography Manual: 2017 Deluxe Edition vs. 2017 Community Edition

When I installed PiezoDN, it came with a manual called the “The Piezography Manual 2017 Deluxe Edition.” Now I see that the Community Edition comes with a manual called “The Piezography Manual 2017 Community Edition”. Both are marked as “Version 2017.v1.” The Deluxe Edition has a long chapter on digital negatives which is lacking in the Community Edition. Is that the only difference? In other words, if I have the Deluxe manual, can I ignore the Community manual?

That’s the only difference.
