With EE2, Zoo Visitor was easy to install.

the lack of documentation makes it very difficult to install Visitor on EE3.

Without the documentation I can't understand this error message:

> An anonymous Guest member does not exist or is not linked with Visitor, go to the Visitor settings and select a member you want to use as anonymous Guest member.

I don't understand this error message too, because Visitor has created and anonymous Guest member.[![error message about the anonymous Guest Member][3]][3]


If I click on install this messager error appears:

The settings options is not working.
Does someone already has ever encountered these problems?
