The readme specifically states:

Theseus' Ship can be used as a drop-in replacement for KWin inside a KDE Plasma Desktop session. After installation and a system restart the Theseus' Ship binary will execute. All configuration, plugins and shell interaction transfer over.

The last part is not true. After an install (which removed kwin) I get back to my session and the zoom is gone. Everything is tiny on my 3000 pixel, 14" laptop.

The display config (monitors kcm) doesn't work, probably incompatible dbus interface (wild guess, that).

Now, I'm fine with me needing to configure stuff in theseus, don't get me wrong, but I need some docs to explain how. Please provide them. In a wiki here is good enough!
