First, you need to build the Shepherd from source.

git clone https://git.savannah.gnu.org/git/shepherd.git
cd shepherd
autoreconf -vif

In the README there's instructions on how to configure and build it.

After building, you need to put a shepherd.scm config at /usr/local/etc/shepherd.scm or a different location
specified with the --config=FILE option for the Shepherd.

Here's an example shepherd.scm config:
https://lists.gnu.org/archive/html/guix-devel/2022-01/msg00279.html

I've attached the shepherd-init wrapper script I use to do some initialisation before running shepherd as init.

After that, I added the following to /etc/default/grub to use the Shepherd as the default init system:
GRUB_CMDLINE_LINUX="init=/usr/local/sbin/shepherd-init"


Note that in the future 1.0 release of the Shepherd, the GOOPS interface will be removed and the old configuration format above won't work anymore.
I plan on updating from 0.8.1 to the 0.10.x release so that I can update my config to the nicer format[1] before then.
