PMpro implement on site? login/registration functionality?

Hi,

I have PMpro and WPcourseware and the WP Courseware Paid Memberships Pro Add On installed. I can see how to use it all but how do I actually implement it on my site? Where does it show up? And do I need to use another plugin for registration and login/out functionality?
