> As of now, it is only possible to deploy Phyllome OS using an [**offical Fedora ISO file**](https://getfedora.org/en/server/). It you don't have a USB flash drive ready to use, please go back to the last section.
*This page is intended for users that would like to install Phyllome OS permanently on their computer. Installing Phyllome OS means booting from a [bootable USB flash drive](/deploy/medium) and fetching [an online kickstart file](https://raw.githubusercontent.com/PhyllomeOS/phyllomeos/main/leaves/flat-dhi.cfg). A kickstart file contains instructions to automatically deploy an operating system. This is a **destructive** process so please be cautious.*
*If you wish to learn more about how kickstart files are used to create Phyllome OS, please have a look at [the official git repository](https://github.com/PhyllomeOS/phyllomeos).*
* A wired Internet connection is required. A file will be fetched online during the installation process.
* A storage device. The kickstart file will look for a storage device and install Phyllome OS. If there is no disk available, the installation will fail.
The following section illustrates how to change the boot order *temporarily*. The process to change the boot order depends on your current computer platform. Please follow the instruction that matches your platform.
### macOS
* Make sure that your computer is turned-off.
* Plug the USB flash drive loaded with the official Fedora ISO.
* Locate the <kbd>Alt</kbd> / <kbd>Option</kbd> key on your keyboard.
* Turn your computer on and immediately press the <kbd>Alt</kbd> / <kbd>Option</kbd> key continuously.
* The startup manager should appear after a few seconds.
* Click on the option called *EFI* and the GRUB splash screen will appear. Go to the section below to learn what to do next.
> GRUB is universal bootloader that ship with many Linux distributions. It is a software made to find and load operating systems during a boot process.
One needs to alter the GRUB instructions before the USB flash drive can load the Anaconda Installer, which is normally used to install Fedora and other related distributions. If Fedora is already installed on your computer, and if your GRUB is not password protected, which is the default behavior, you may also be able to follow the instructions below.
> GRUB defaults to the US keyboard layout. Have a look at [this online ressource](https://en.wikipedia.org/wiki/QWERTY#/media/File:KB_United_States.svg) to find the corresponding keys if you are having a hard time finding the right keystroke
> **Danger Zone**: the next instruction will trigger an automated process that will **destroy** any data located on the internal disk present in your computer.
* Leave a blank space after the `quiet` word and write exactly the following `inst.ks=https://ks.phyllo.me/dii`, then press <kbd>Ctrl</kbd> + <kbd>x</kbd> simultaneously. This command will trigger the automated installation of Phyllome OS.
> The shortened URL `https://ks.phyllo.me/dii` points to the latest Desktop version of Phyllome OS, tweaked for Intel CPUs and GPUs. The kickstart file is available here: https://raw.githubusercontent.com/PhyllomeOS/phyllomeos/main/leaves/flat-dhi.cfg. Any valid kickstart file may be used.
