How to install or get Polyphemus ?

[labordep]

I don't understand the way to get (or install) and use Polymphemus on my PC.

I have tried that :

Metacello new
   baseline: 'Polyphemus';
   repository: 'github://hogoww/Polyphemus:main';
	onConflictUseIncoming;
	ignoreImage;
   load.

But an exception is raised during the loading (DirectoryDoesNotExist: Path ... Pharo/images/Polyphemus/pharo-vm/smalltalksrc.

Can you add some documentation or a link to get it ?
