     1. Download and install `usbmuxd`. It may be preinstalled with your distribution, otherwise you can install it with your package manager: a Google search for "install usbmuxd [distribution name]" might help you.
     2. Download and install iloader for your distribution. It is available as a [DEB](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-amd64.deb) for Debian/Ubuntu, [RPM](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-x86_64.rpm) for Fedora/openSUSE, and as an [AppImage](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-amd64.AppImage) for others. Additionally, for ARM processors there are also [DEB](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-arm64.deb), [RPM](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-aarch64.rpm), and [AppImage](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-aarch64.AppImage) builds. (There are also community-maintained packages, such as [this one on the Arch Linux AUR](https://aur.archlinux.org/packages/iloader-bin), but please know that we cannot guarantee their safety or security. You should always do your due diligence before installing unknown packages onto your system.)

+    :::warning
+    **This will not work with enrolled Chromebooks if the Administrator disabled it, and may not work with old Chromebooks.** Usually enrolled Chromebooks have `Linux development environment` disabled, or for old Chromebooks, they do not provide such options.
+    :::
+
+    1. Enable `Linux development environment`. You can read the [Set up Linux on your Chromebook](https://support.google.com/chromebook/answer/9145439) guide by Google to see how to set it up, following the `Turn on Linux` steps.
+    2. Ensure all packages are updated by opening the Terminal, running the following command: `sudo apt-get update && sudo apt-get dist-upgrade`
+    3. Open the Files app, right click on the `Downloads` folder in the left sidebar, and click `Share with Linux`. (It will be shared in `/mnt/chromeos/MyFiles/Downloads`)
+    4. Download and install `usbmuxd` and `fuse`. It may be preinstalled with your distribution, otherwise you can install it with your package manager: `sudo apt-get install usbmuxd fuse`
+    5. Download and install iloader. It is available as an [AppImage](https://github.com/nab138/iloader/releases/latest/download/iloader-linux-aarch64.AppImage). Download the file to your Downloads folder.
+    6. If `usbmuxd` isn't already started, run the following command in the Terminal: `sudo systemctl restart usbmuxd`
+    7. Navigate to `Manage USB devices` (in **Settings** -> **About ChromeOS** -> **Developers** -> **Linux development environment**), then connect your iPhone, iPad, or iPod touch (iDevice) to your Chromebook via a USB cable. As soon as you see the device, **quickly enable it from the list**. If you are prompted on your iDevice, trust the computer and enter your passcode.
+    :::note
+    **Enabling the iDevice __quickly__ in Manage USB devices is necessary** due to a bug with the `Linux development environment`. ChromeOS automatically claims the iDevice (which is why it appears in the Files app), preventing the Linux container from seeing it. Manually enabling it in **Manage USB devices** quickly before ChromeOS claims the iDevice will pass control to the container instead. You can follow **Step 8** to verify the container sees the iDevice.
+    :::
+    8. Verify the `Linux development environment` recognizes your iDevice by running `lsusb` in the Terminal. Your iDevice should appear in the list. If it doesn't, try unplugging, and repeating the previous step.
+    :::tip
+    The output for `lsusb` should look something like this, with iPhone (or similar device) being an existing entry:
+    ```
+    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
+    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
+    Bus 001 Device 008: ID 05ac:12a8 Apple, Inc. iPhone 5/5C/5S/6/SE/7/8/X/XR
+    ```
+    The exact device name and bus/device numbers may vary, but they are not significant.
+    :::
+    9. Run the following command in the Terminal to allow iloader to be executable, and to launch iloader (ensure the filename matches what was downloaded):
+    ```
+    cd /mnt/chromeos/MyFiles/Downloads
+    chmod +x iloader-linux-aarch64.AppImage
+    ./iloader-linux-aarch64.AppImage
+    ```
