+## Podman systemd files
+
+Rather than copying compose files or running podman run as systemd services you can
+generate quadlet files to define containers that run at boot.
+
+Podlet generates quadlets - systemd files specifically for containers.
+
+You generate quadlets from compose files like so:
+
+```bash
+docker run \
+    -v ./compose:/compose \
+    -v ./quadlets:/quadlets \
+    quay.io/k9withabone/podlet \
+    -f /quadlets \
+    -i \
+    --overwrite \
+    compose /compose/grafana-compose.yaml
+```
+
+Copy these files to `/usr/share/containers/systemd/`
+
+### iperf3
+
+```bash
+podman run \
+    -v ./compose:/compose \
+    -v ./quadlets:/quadlets \
+    quay.io/k9withabone/podlet \
+    -f /quadlets \
+    -i \
+    --overwrite \
+    compose /compose/iperf3-compose.yaml
+```
+
+### pihole
+
+```bash
+podman run \
+    -v ./compose:/compose \
+    -v ./quadlets:/quadlets \
+    quay.io/k9withabone/podlet \
+    -f /quadlets \
+    -i \
+    --overwrite \
+    --wants network-online.target \
+    --after network-online.target \
+    compose /compose/pihole-compose.yaml
+```
+
+### Grafana
+
+```bash
+podman run \
+    -v ./compose:/compose \
+    -v ./quadlets:/quadlets \
+    quay.io/k9withabone/podlet \
+    -f /quadlets \
+    -i \
+    --overwrite \
