== Introduction ==

Quintagroup Captcha Core allows configure captchas on your Plone site: its size, color, etc. This product does not add captcha to your Plone site, it only allows
its configuring. To protect your Plone forms with captcha - use [wiki:quintagroup.plonecaptchas quintagroup.plonecaptchas] package.

== Usage ==

After its installation you'll see '''Plone captchas setup''' option under Add-on Product Configuration in Site Setup.

Here you can select what kind of captchas you want to appear: either static or dynamic. In case you select dynamic captchas, in the dynamic captchas image setup options you can configure captchas look by using different font sizes, background and font colours, period, amplitude, random values. As a result your captchas field can look like the following:
