[Plugin: WP-reCAPTCHA] how to integrate it inside my theme/plugin?

Hi there,

I searched a lot about this but with no answer: how to integrate this plugin in my templates and custom forms? is this plugin pluggable?

I searched for how to hook this recaptcha to custom theme, I found this post but didn’t work and the docs says nothing about it!… strange.

in the plugin folder of recaptcha I searched for functions; check_recaptcha_new, display_recaptcha -they don’t exsit.

I use version 3.1.3 of reCaptcha and latest wordpress version.
