 Install podman:
 
 ```sh
-sudo apt install podman
+sudo apt-get update && sudo apt-get install -y podman

+Create the data directories (`/data`) for persisting Forgejo runner configurations and cache:
+
+```sh
+sudo mkdir -p /data/.cache /data/.config
+sudo touch /data/.runner
+
+sudo chown -R $UID:$UID /data
+sudo chmod -R 700 /data

 To enable automatic start-up on boot, your user needs to have "lingering" enabled in SystemD:
 
 ```sh
 sudo loginctl enable-linger $USER
+```
+
+## Register the Runner
+
+On your Forgejo server's `Site administration` page, go to `Action` then `Runners`. Click `Create a new runner` and copy the token.
+
+Back on your Forgejo Runner host, run:
+
+```sh
+podman exec -it systemd-forgejo-runner /bin/sh
+
+# Run inside the container and follow the instructions:
+# (I recommend setting the label 'docker')
+forgejo-runner register
+
+# Confirm the .runner file has been written to:
+cat .runner
+
+# Write out default configurations:
+forgejo-runner generate-config > .config/config.yml
+
+exit
+```
+
+For building containers, you will need to tweak the runner's configurations to create privileged containers and avoid creating a nested network stack. Don't worry, this is still sandboxed inside the `podman-runtime` container.
+
+```diff
+# sudo vim /data/.config/config.yml
+
+container:
+-  network: ""
++  network: host
+-  privileged: false
++  privileged: true
+```
+
+Revert the runner's quadlet to launch the daemon:
+
+```diff
+# vim forgejo-runner-quadlet/quadlets/forgejo-runner.container
+
+- # Exec=/bin/sh -c "sleep 5; forgejo-runner daemon -c .config/config.yml"
+- Exec=/bin/sh -c "while : ; do sleep 1 ; done ;"
++ Exec=/bin/sh -c "sleep 5; forgejo-runner daemon -c .config/config.yml"
++ # Exec=/bin/sh -c "while : ; do sleep 1 ; done ;"
+```
+
+Reload the quadlet and restart it:
+
+```sh
+systemctl --user daemon-reload
+systemctl --user restart forgejo-runner.service
+```
+
+Now, in the Forgejo server Runners page, you should see your new runner as "Idle".

This has to be created manually because the automatic token `FORGEJO_TOKEN` does not have this permission. Track [this feature request](https://codeberg.org/forgejo/forgejo/issues/6198).
