 If a package name is wrong on your distro, the library list above is what matters, and an [issue](https://github.com/Fi3w0/TideWM/issues/new/choose) helps everyone.
 
+**Without systemd** (Void, Artix, Gentoo OpenRC, ...), libseat needs a seat manager: run seatd and add your user to its group, or use elogind. On Void with runit:
+
+```bash
+sudo ln -s /etc/sv/seatd /var/service/
+sudo usermod -aG _seatd "$USER"   # log out and back in
+```
+
+There is no systemd user bus, so start TideWM from a TTY as `dbus-run-session TideWM` if portals, screen sharing or tray apps need a session bus. The systemd environment export and `tidectl doctor`'s journal and core-dump checks quietly skip when systemd isn't there.

 Optional: [`xwayland-satellite`](https://github.com/Supreeeme/xwayland-satellite) for X11 apps (`xwayland.enabled = false` turns it off).
