Rsync-Plugin, Version and Documentation

Hi,

I try to use the rsync plugin for drone.io. I found several different documentations:

The first states

The plugin authenticates to your server using a per-repository SSH key generated by Drone. You can find the public key in your repository settings in Drone. You will need to copy / paste this key into your ~/.ssh/authorized_keys file on your remote machine.

In my drone v0.6 settings panel is no public key generated by drone. Where can I find it. Do I need to update to drone v0.8.1? (This is not really trivial).

Btw: I suggest to add at least the version number to the documentation page.
