integration PunBB with start login (codeigniter)

Hello.

I know that my question has been up a thousand times by other members. Me and my developers have tried to embrace all that is at punbb.wiki to integrate but we must not for that.

We are currently integrating a forum (PunBB) with a login on the homepage but it is not so good. We have stuck you could say. We want the database of the forum will pick up members from datbasen Membership page. When the user logs on to the home page it must also be seen in the forum.

Does anyone have integrated PunBB with CodeIgniter and know how to do and where to start?
