+[Unit]
+Description=Git Server UI
+After=network.target
+
+[Service]
+User=apache
+WorkingDirectory=/srv/git/git-server-ui
+ExecStart=/usr/local/bin/gunicorn --workers 3 --bind 0.0.0.0:8000 --chdir /srv/git/git-server-ui wsgi:app
+Restart=on-failure
+
+[Install]
+WantedBy=multi-user.target
+````

+
+```console
+$ sudo git config --system init.defaultBranch main
+```
