# Required setup for self-hosted runner:
# 1. Install dependencies:
#         sudo pacman -S qemu-user-static qemu-user-static-binfmt docker
# 2. Add runner to docker group:
#         sudo usermod -aG docker forgejo-runner
# 3. Restart runner service to apply group membership:
#         sudo systemctl restart forgejo-runner
# 4. Install uv and ruff for the runner user
# 5. Login to GitHub Container Registry:
#         echo "ghp_YOUR_TOKEN_HERE" | sudo -u forgejo-runner docker login ghcr.io -u TheLovinator1 --password-stdin
