Meant to do this years ago. Finally decided it had to be done. Hope it helps.

Worthy of note

I guess I'm going to send a few people here. Maybe you can make a short tutorial like this on typesetting? People are so damn lazy to read the guide from here even though it's a good tutorial: https://fallensyndicate.wordpress.com/typesetting-tutorial/

The fact you made this makes me feel really bad, but I very much appreciate it. Thank you.

I tried your guide. 2 quick notes
p5 don't you mean aspect ratio, not resolution
page6 Adjust Shadow to 'erase' background artifact and shadow from back page
page8 there are 2 JPG options avaliable, JPG- JPEG and JPG Guetzli. My laptop can't render Guetzli (whatever is that) so choose JPEG
