I want to get started with Buddypress

Hi,

I need to get started with Buddypress installed onto two of my websites. They both have the latest Wordpress installed onto it. However, I just don't know where to start.

With Buddypress do you have to install multisite? Also, is there a step by step tutorial somewhere that I can use to enable buddypress onto my two websites? Where do I start?

Thanks,
Virgil
