+# pizauth on Linux
+
+Pizauth comes with a systemd unit and example configurations. To start pizauth:
+
+```sh
+$ systemctl --user start pizauth.service
+```
+
+If you want `pizauth` to start on login, run
+
+```sh
+$ systemctl --user enable pizauth.service
+```
+
+In `/usr/share/examples/pizauth/systemd-dropins` are templates for saving
+pizauth dumps encrypted with `age` and `gpg`. To use them, run
+
+```sh
+$ systemctl --user edit pizauth.service
+```
+
+and paste whichever of the templates suits you in the file `systemctl` opens.
+Make sure to modify the references to private/public keys/IDs in the temalpte
+file to point to your keys/IDs.
