+Before using this modul, be sure to register at the reCaptcha providers website in order to get your client secret and site key. These are required to use this module. Register at:
+* [Google reCaptcha](https://www.google.com/recaptcha/admin)
+* [hCaptcha](https://hcaptcha.com)
 
 Once you have your client secret and site key, you should create an instance of `ReCaptcha`:
 
 ```nim
 import recaptcha

+let captcha = initReCaptcha("MY_SECRET_KEY", "MY_SITE_KEY", Google)

-In most cases, captchas are used within a HTML `<form>` element. In this case, the user's response will be available within the `g-recaptcha-response` form parameter.
+In most cases, captchas are used within a HTML `<form>` element. In this case, the user's response will be available within form parameter named `g-recaptcha-response` for `Google` and `reCaptha.net` and within `h-recaptcha-repsonse` for `hCaptcha`.
 
 You may also optionally pass the user's IP address along to reCAPTCHA during verification as an extra check:
