Wordpress Integration.

I currently have a WordPress based website. To what degree is Xenforo able to integrate with the content? Are the user accounts able to be linked? Are the shoutbox and user control panels able to be displayed perhaps as widgets? I cannot tell if Xenforo is a completely stand alone product or whether it can be installed and integrated into an existing WordPress website.

Any clarifications would we wonderful

Thanks in advance,
I need to remember to search the forums and not the website before I post. Please don't bother answering these questions at this time as there are several threads that may have the information that I will read first.
