+You can edit which tty Ly will start on by editing the `tty` option in the configuration file.

+If you choose a tty that already has a login/getty running (has a basic login prompt), then you have to disable the getty so it doesn't respawn on top of ly

 ## Arch Linux Installation
 You can install ly from the [AUR](https://aur.archlinux.org/packages/ly), using yay for example:
