+### Option 3: Quadlet
+
+Before setting up the container, you will need to generate configs. Follow the instructions in the earlier docker steps, optionally replacing `docker` with podman. Place the generated configs in `/etc/containers/config/isponsorblocktv/`
+
+You can set up a quadlet service using the following config:
+
+```systemd
+[Unit]
+Description="Sponsorblock for networked youtube clients"
+Wants=network-online.target
+After=network-online.target
+
+[Install]
+WantedBy=multi-user.target default.target
+
+[Service]
+Restart=always
+TimeoutStartSec=900
+
+[Container]
+Image=ghcr.io/dmunozv04/isponsorblocktv:latest
+Volume=/etc/containers/config/isponsorblocktv:/app/data
+```
+
+Place that in a file at `/etc/containers/systemd/isponsorblocktv.container`, run `systemctl daemon-reload`, and you should now have a systemd service titled `isponsorblocktv` that you can start, stop, and enable/disable the same as any other systemd service.
