Installing reCAPTCHA III

[Koga73]

Hello, i have recently been hired as a forum helper for this site:
www.fallenangelscommunity.com
and I've been cleaning up alot of their stuff, but one thing that really bugged me was the damn spambots. Now, i figured nothing would happen if i just changed the security questions, but today, a bot registered on the site and made a post. This is seriously bugging me out, so i figured, why not installing a captcha plugin just to make it a little harder for them and maybe they would most likely not pick this forum out to bother.

This is the plugin i want to install: http://mods.mybb.com/view/recaptcha
MyBB Version: 1.6.11
PHP Version: 5.3.22

My question is.. how do i install this? I have no idea where to start out.
I hope i placed this in the right section.. thank you for your time!

if the forum is of latest version (1.6.11) then there is no need to install that ReCaptcha plugin.
MyBB 1.6.11 has the ReCaptcha by default. you have to configure it and add the keys for it

admin panel >> configuration >> settings >> general configuration --> CAPTCHA Images for Registration & Posting
select ReCaptcha and add the keys
