General Usage

Before you can start using the view helpers or validators, you need to obtain valid API keys from either [reCAPTCHA](https://developers.google.com/recaptcha) or [hCAPTCHA](https://www.hcaptcha.com/). Define the keys somewhere in your typoscript for the website:

Please note that defining the keys in typoscript is not required. The keys can be specified in the view helper and validation definition, too. Using typoscript is a more global way if you have multiple forms to be secured by a CAPTCHA.

reCAPTCHA and hCAPTCHA can be used parallel in the same setup.
