Welcome to the Luna operating system! You are running on the default user account, selene. If you are familiar with Unix-style operating systems (like Linux or *BSD), you should be able to use the Luna terminal without much problems. Following the traditional Unix filesystem structure, programs are installed in /usr/bin (/bin is a symlink to /usr/bin). The command `ls /bin` will show all commands available on your current Luna installation. Currently, because of driver limitations, the root file system is mounted read-only. Your home folder is writable, but volatile; it is created and populated on boot, and its contents will vanish after a reboot. The system is booted using the 'init' program. You can read its configuration files in the /etc/init directory to learn more about the boot process. Luna is free software, released under the BSD-2-Clause license. The license is included in the LICENSE file in your home directory. View the source code and read more about Luna at https://git.cloudapio.eu/apio/Luna.
