About what. What exactly did you miss?

You can get the list of needed dependencies from the CI files
(.gitlab-ci.yml of each project, they're guaranteed to be up to date) or
the debian packaging in the very same repo.  You can also grab packages
for i386, armhf and aarch64 from here

Either you install the gnome apps used (check
https://source.puri.sm/Librem5/librem5-base) or you modify the list of
applications. See the gsettings file that is shipped with phosh, you can
either use the gsettings command or dconf-editor.

The users's password needs to be a six digit pin atm.

See above. If you want to replicate this it's best to grab the qemu
image and see how it does things and do the same on your rpi.

Check the qemu image. The phosh deb installs a systemd unit which is in
debian/phosh.service. You can use overrides if you want to use another
user, e.g. I use:

$ cat /etc/systemd/system/phosh.service.d/override.conf
