# Systemd Integration
Run dimension as a systemd service and configure to start at boot.
* Create service unit file. Save [systemd.matrix-dimension.service](https://github.com/turt2live/matrix-dimension/tree/master/config/systemd.matrix-dimension.service) to a systemd system path (e.g., `/etc/systemd/system/matrix-dimension.service`)
* Enable and start the newly created service
```
$ systemctl enable matrix-dimension.service
Created symlink /etc/systemd/system/default.target.wants/matrix-dimension.service → /etc/systemd/system/matrix-dimension.service.
```
* Try starting it up and checking the status for errors
```
$ systemctl start matrix-dimension.service
$ systemctl status matrix-dimension.service
```
* Reload systemd if any changes to the service file are necessary
```
$ systemctl daemon-reload
$ systemctl restart matrix-dimension.service
```
* View logs
```
