+- Create a systemd service file in /etc/systemd/system/admin-group-manager.service with the following content:
+	```ini
+	[Unit]
+	Description=Admin Group Manager worker
+	After=network.target
+
+	[Service]
+	ExecStart=/opt/admin-group-manager/taskprocessing.sh
+	Restart=always
+
+	[Install]
+	WantedBy=multi-user.target
+	```
+
+
+- Create a shell script in /opt/admin-group-manager/taskprocessing.sh with the following content and make sure to make it executable:
+
+	```bash
+	#!/bin/sh
+	echo "Starting Admin Group Manager worker $1"
+	cd /path/to/nextcloud
+	sudo -u www-data php occ background-job:worker 'OCA\AdminGroupManager\BackgroundJob\EnableAppsForGroup'
+	```
+
+- Enable and start the service:
+  ```bash
+  systemctl enable --now admin-group-manager.service
+  ```
+- Check if is working fine:
+	```bash
+	systemctl list-units --type=service | grep admin-group-manager
+	```
+- Check execution log:
+	```bash
+	journalctl -xeu nextcloud-ai-worker.service -f
+	```
+
 ## How to use
 
 Check the available endpoints installing the app `ocs_api_viewer` and going to Nextcloud web interface at ocs_api_viewer app to verify the endpoints of this app.
