Configuration page - not where Readme.txt says it is

Configuration page is here: admin/user/captcha
- Located under "User Management" in the Admin UI

Readme.txt says it's here: admin/settings/captcha
- Located under "Site Configuration" in Admin UI (was here in older versions)

"Configuration:
The configuration page is at admin/settings/captcha, here you can configure
the captcha module and enable captchas for the desired forms."
