 **2.** The software includes an in-app self-update command / feature. It will help you stay up-to-date with the latest version of the software. Updates are on-demand, so don't worry about undesired updates. The project moves very fast and new features become available regularly, particularly if you choose to run the software in the ```develop``` branch (you may switch branches from within the app).

It may work without admin powers depending on your setup, particularly if you are running the command on a folder where you've got write permissions.

+# Running Superalgos on a headless linux server as a daemon
+
+If you’re running Superalgos on a headless linux server like a Raspberry Pi, you might want to run it as a daemon so it isn’t attached to your current login session. The easiest, most standard way to go about this is probably using `systemd`. Most linux distributions use it as default init system/service manager.
+
+## Using `systemd`
+
+Create a `superalgos.service` file looking like this (change `<user>` to your user name and `/path/to/Superalgos` to your Superalgos folder, for instance `/home/John/Superalgos`):
+```
+[Unit]
+Description=Superalgos client
+
+[Service]
+Type=simple
+User=<user>
+WorkingDirectory=/path/to/Superalgos
+ExecStart=/usr/bin/node run minMemo noBrowser
+
+[Install]
+WantedBy=multi-user.target
+
+```
+There is no need to run Superalgos as root so we’re running it as a user. The `minMemo` option assumes you’re running on a small machine like a Raspberry Pi, while `noBrowser` makes sense for running daemonized.
+
+Now, as root (or using `sudo`), put the file `superalgos.service` you just created in `/etc/systemd/system/` and issue the command
+```
+systemctl enable superalgos
+```
+This will install the service so that Superalgos is started on boot. To start it manually, do (again as root or with `sudo`)
+```
+systemctl start superalgos
+```
+
+To see the output of Superalgos, use
+```
+journalctl -u superalgos
+```
+or to follow the output,
+```
+journalctl -u superalgos -f
+```
