# genie > Set up and use a "bottle" namespace to run systemd under WSL (Windows Subsystem for Linux). > To run these from Windows rather than an already-running distribution, precede them with `wsl`. > More information: . - Initialize the bottle (run once, at start): `genie {{[-i|--initialize]}}` - Run a login shell inside the bottle: `genie {{[-s|--shell]}}` - Run a specified command inside the bottle: `genie {{[-c|--command]}} {{command}}`
