 You can skip this step if you don't use systemd.
+1. Copy the service template file:

-- edit the content of ```WorkingDirectory``` in the ```searxng-docker.service``` file (only if the installation path is different from /usr/local/searxng-docker)
-- Install the systemd unit:
-  ```sh

-  systemctl start searxng-docker.service
-  ```
+4. Start the service:
