+## Setting up Systemd
+
+If you want to deploy your bbgo binary to a linux system, you could use the systemd to launch your daemon.
+
+To do this, add service file into the directory `/etc/systemd/system/bbgo.service` with the following content:
+
+```shell
+[Unit]
+After=network-online.target
+Wants=network-online.target
+
+[Install]
+WantedBy=multi-user.target
+
+[Service]
+WorkingDirectory=/home/bbgo
+# KillMode=process
+ExecStart=/home/bbgo/bbgo run
+User=bbgo
+Restart=always
+RestartSec=60
+```
+
+Then, to load the service file, you need to run:
+
+```shell
+systemctl daemon-reload
+```
+
+And then you can start your service by running enable and start:
+
+```shell
+systemctl enable bbgo.service
+systemctl start bbgo.service
+```
+
+To stop your service, you can run:
+
+```shell
+systemctl stop bbgo.service
+```
+
