Open the guidebook

The guidebook pages and the errors guide are for people who bought the course. Paste your license key here and this browser can open them for the next 12 hours.

Where your license key is

A license key is the long code Gumroad gave you when you bought the course. It looks like four blocks of letters and numbers with dashes between them. Two places have it:

• Your receipt. Gumroad emailed it to the address you paid with, and the key is printed in it.
• Your Gumroad library. Sign in with that same email address, open this product, and the key sits at the top of the page.

Copy the whole code, dashes included, and paste it into the box above.

What happens when you press the button

This site asks Gumroad whether that key belongs to a purchase that still stands. When it does, the guidebook opens for 12 hours and your browser keeps the key so you can skip this page next time. Each new visit is checked with Gumroad again, so a refunded purchase closes these pages the same day. The files you downloaded stay yours either way.
