Basic Usage

You embed the Captcha widget on your site. For example, on a login form. The user answers Captcha challenge. They get a passcode from captcha server that is embedded in your form. When the user clicks Submit the passcode is sent to your server in the form. Your server then checks that user passcode sent. Captcha server says it is valid and credits your account. Your server now knows the user is not a bot and lets them log in. Pretty simple!
