Where to find your license key?

The license key is generated by Gumroad and it looks like this: 7BDE50F1-FE6545E6-A8FD5AD4-A7A300B7. After you bought the book you can find your key in several places:

1. Confirmation email

It is included in the confirmation email you got when you bought the book.

If you bought the book before 2022 Oct then license keys weren't enabled. Try the next method in that case.

2. In your Gumroad account

In your Gumroad account, find it in the Library/Product's download page.

3. Have Gumroad email it to you
