+# Creating a new ForgeJo Runner Host
+
+## Machine Setup
+
+### 1. Install Ubuntu (24.04)
+
+For example on the Hetzner cloud.
+
+### 2. Create a new user for the runner
+
+Since we don't want to the new forgejo runner to be ``root`` on out machine, we create a new user for it:
+```bash
+# As root
+useradd -s /bin/bash --create-home forgejo-runner
+loginctl enable-linger forgejo-runner
+```
+
+### 3. Install podman (rootless)
+
+```bash
+# As root
+apt install -y podman
+echo "forgejo-runner:10000:12000" >> /etc/subuid
+echo "forgejo-runner:10000:12000" >> /etc/subgid
+```
+
+#### Enable Podman docker-socket on user
+
+```bash
+# As root
+apt install -y systemd-container
+machinectl shell --uid forgejo-runner # <-- This is basically "sudo -Hi XXX" but makes sure the systemd container is switched too.
+```
+
+```bash
+systemctl enable --user podman.socket
+echo 'export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock' >> ~/.profile
+```
+
+#### Automatic podman cleanup on reboot
+
+```bash
+crontab -e
+```
+```cronexp
+@reboot podman system cleanup --all --force
+```
+
+### 4. Install the forgejo-runner
+
+```bash
+# As forgejo-runner
+# Verify these URLs are still the version you want to install!!!
+DOWNLOAD_URL="https://code.forgejo.org/forgejo/runner/releases/download/v5.0.4/forgejo-runner-5.0.4-linux-amd64"
+SIG_URL="https://code.forgejo.org/forgejo/runner/releases/download/v5.0.4/forgejo-runner-5.0.4-linux-amd64.asc"
+gpg --keyserver keys.openpgp.org --recv EB114F5E6C0DC2BCDD183550A4B61A2DC5923710 # Installs the signing key used by forgejo for their releases
+wget -O forgejo-runner "$DOWNLOAD_URL"
+wget -O forgejo-runner.asc "$SIG_URL"
+gpg --verify forgejo-runner.asc forgejo-runner
+# The output should now contain the following:
+# Good signature from "Forgejo <contact@forgejo.org>"
+#		aka "Forgejo Releases <release@forgejo.org>"
+
+mkdir -p ~/.local/bin
+mv ./forgejo-runner ~/.local/bin/forgejo-runner
+chmod 750 ~/.local/bin/forgejo-runner
+```
+
+### 5. Configure and register the forgejo-runner
+
+__The official runner registration is__ [here](https://forgejo.org/docs/v8.0/admin/runner-installation/#standard-registration)
+Or, if you're volunteering another runner for our instance, please contact us to receive the necessary registration information. :)
+
+```bash
+# As forgejo-runner
+forgejo-runner generate-config > config.yml
+
+# We're about to enter secrets into the terminal, disable history:
+set +o history
+RUNNER_INST_URL="https://git.forsaken-ashbirds.net"
+RUNNER_NAME="<PLEASE ENTER A UNIQUE NAME FOR YOUR RUNNER HERE!!!>"
+RUNNER_TOKEN="<The token from the UI>"
+RUNNER_LABELS="ubuntu-24.04,docker,podman,self-hosted" # Update these labels if you intend to change stuff!
+
+# Re-enable history :)
+set -o history
+forgejo-runner register --instance "$RUNNER_INST_URL" --name "$RUNNER_NAME" --token "$RUNNER_TOKEN" --labels "$RUNNER_LABELS" --no-interactive
+# You should see the following afterwards:
+# INFO Runner registered successfully
+```
+
+#### Check the runner is working
+
+```bash
+# As forgejo-runner
+mkdir -p ~/.config/systemd/user
+# Download the file "docs/forgejo-runner.service" from this repository to "~/.config/systemd/user"
+systemctl --user enable --now forgejo-runner
+```
+
+__Go into Forgejo and check that your runner is shown as UP__.
