how to integrate Network theme with budypress

Hi guys

I plan to create a community and as far as a read the way to go is with budypress which I already installed and activated, thing is a have these issues:

According to this link

once activated I could not see the welcome to budypress and budypress settings page

also the documentation says once installed a toolbar will appear but I can´t see the toolbar

probably I´m missing something.

please your help.
