how to add basic membership with regsitration?

hello,

I have the following problem that I cannot figure out:

I am using paid membership pro with kleo. I would like to add a basic free membership with registration, but I cnanot figure out how to do that.

Also, on the theme options membership page: what is the difference between “not logged in” and “not member”?

Somebody can be logged in, but not a member?

Because then a logged in not member could be a basic membership for me…. is that correct?

THanks.
