MyBB Community Forums

How do I put the Wordpress header on to my MyBB forum? I know it will involve editing css so a step by step would be really helpful I am clueless.

I am working on MyBBPress, which will make your MyBB forum look like a Wordpress blog.

So once this is done it will allow me to put that header onto MyBB? Any ideas on how long this is going to take?
