Not understanding how to access the register form for this plugin

I have installed it.
I see no info on how to access the register form.
I visited domain.com/wp-register.php

this was still the old wordpress form.
only contains fields for username and email.
Just as it has always contained.
I see no new pages for the form.
I see no shortcodes to embed it.
I see no directions on how it is accessible.

Please let me know how to access the register form.
