Looking for a Manual for the Directory plugin

Hi, I'm an absolute beginner with Directory and just looking arround to find out, what i can do with it.

Is there any manual where I can read about the functions.

I've read the readme.txt, but that didn't help.

>You can find these options inside your WP-ADMIN panel under the top level menu "Appearance".

I didn't find "WP-ADMIN panel" and no menu "Appearance"

I need some hints what these "seetings" mean and do and where I can change the "Look" and the "Output Items".

For example turn off "Posted on ... by ....", turn off "Average rating"

It's no problem for me to do it in the source code, i've only have to find the file.

Regards Walter
