How to add to ipb?

Question

IPB

I'm still studying, and I have almost finished work on the site and there is work on the forum. And I’ve just started and already a snag and I can’t understand, I’ve been surfing the Internet for about 30 minutes and I still don’t understand even (although maybe I’m already stupid after 5 hours of working on the site) I can’t add the “Home” button here
