Questions
Is it the same as the website?
No. The site explains each concept in depth; the Field Guide is the short, situation-first version you keep next to a decision, plus 25 more models than the site has today, the bias fixes and the 12 stacks.
What format is it?
A PDF (reads well on any screen and prints on Letter or A4) and an EPUB for Apple Books, Kobo and most e-readers. For Kindle, send the EPUB with Send to Kindle.
How do I get the files?
Right after paying you land on your downloads page, and we email you the same private link. Lost it? Resend it here.
Can I get a refund?
Yes, within 7 days of buying, for any reason. Reply to your order email or write to support@mentarium.io.
