+The downloaded file will be named `wg-portal` and can be moved to a directory of your choice, see [Install](#install) for more information.
+
+### Unreleased versions (master branch builds)
+
+Unreleased versions can be fetched directly from the artifacts section of the [GitHub Workflow](https://github.com/h44z/wg-portal/actions/workflows/docker-publish.yml?query=branch%3Amaster).
 
 
 ## Install
 
+The following command can be used to install the downloaded binary (`wg-portal`) to `/opt/wg-portal/wg-portal`. It ensures that the binary is executable.
+
 ```shell
 sudo mkdir -p /opt/wg-portal
 sudo install wg-portal /opt/wg-portal/
 ```
 
-## Unreleased versions (master branch builds)
+To handle tasks such as restarting the service or configuring automatic startup, it is recommended to use a process manager like [systemd](https://systemd.io/). 
+Refer to [Systemd Service Setup](#systemd-service-setup) for instructions.

+## Systemd Service Setup
 
+> **Note:** To run WireGuard Portal as systemd service, you need to download the binary for your architecture beforehand.
+> 
+> The following examples assume that you downloaded the binary to `/opt/wg-portal/wg-portal`. 
+> The configuration file is expected to be located at `/opt/wg-portal/config.yml`.
+
+To run WireGuard Portal as a systemd service, you can create a service unit file. The easiest way to do this is by using `systemctl edit`:
+
+```shell
+sudo systemctl edit --force --full wg-portal.service
+```
+
+Paste the following content into the editor and adjust the variables to your needs:
+
+```ini
+[Unit]
+Description=WireGuard Portal
+ConditionPathExists=/opt/wg-portal/wg-portal
+After=network.target
+
+[Service]
+Type=simple
+User=root
+Group=root
+AmbientCapabilities=CAP_NET_ADMIN CAP_NET_RAW
+
+Restart=on-failure
+RestartSec=10
+
+WorkingDirectory=/opt/wg-portal
+Environment=WG_PORTAL_CONFIG=/opt/wg-portal/config.yml
+ExecStart=/opt/wg-portal/wg-portal
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Alternatively, you can create or modify the file manually in `/etc/systemd/system/wg-portal.service`. 
+For systemd to pick up the changes, you need to reload the daemon:
+
+```shell
+sudo systemctl daemon-reload
+```
+
+After creating the service file, you can enable and start the service:
+
+```shell
+sudo systemctl enable --now wg-portal.service
+```
+
+To check status and log output, use: `sudo systemctl status wg-portal.service` or `sudo journalctl -u wg-portal.service`.
