+# Setup Sprout for Fedora without Secure Boot
+
+## Prerequisites
+
+- Modern Fedora release: tested on Fedora Workstation 42 and 43
+- EFI System Partition mounted on `/boot/efi` (the default)
+- ext4 or FAT32/exFAT formatted `/boot` partition
+
+## Step 1: Base Installation
+
+Download the latest sprout.efi release from the [GitHub releases page](https://github.com/edera-dev/sprout/releases).
+For x86_64 systems, download the `sprout-x86_64.efi` file, and for ARM systems, download the `sprout-aarch64.efi` file.
+Copy the downloaded `sprout.efi` file to `/boot/efi/EFI/BOOT/sprout.efi` on your EFI System Partition.
+
+Additionally, you will want to install the `edk2-ext4` package, which provides the ext4 filesystem support for Sprout.
+
+```bash
+# Install the edk2-ext4 package which provides ext4 support for Sprout.
+$ sudo dnf install edk2-ext4
+# Create a directory for sprout drivers.
+$ sudo mkdir -p /boot/efi/sprout/drivers
+# For x86_64 systems, copy the ext4x64.efi driver to the sprout drivers directory.
+$ sudo cp /usr/share/edk2/drivers/ext4x64.efi /boot/efi/sprout/drivers/ext4.efi
+# For ARM64 systems, copy the ext4aa64.efi driver to the sprout drivers directory.
+$ sudo cp /usr/share/edk2/drivers/ext4aa64.efi /boot/efi/sprout/drivers/ext4.efi
+```
+
+## Step 2: Configure Sprout
+
+Since Fedora uses the BLS specification, you can use the `bls` generator to autoconfigure Sprout for Fedora.
+
+Write the following file to `/boot/efi/sprout.toml`:
+
+```toml
+# sprout configuration: version 1
+version = 1
+
+# load an EFI driver for ext4.
+[drivers.ext4]
+path = "\\sprout\\drivers\\ext4.efi"
+
+# global options.
+[options]
+# enable autoconfiguration by detecting bls enabled
+# filesystems and generating boot entries for them.
+autoconfigure = true
+```
+
+## Step 3, Option 1: Configure GRUB to load Sprout (recommended)
+
+You can configure GRUB to add a boot entry for Sprout, so you can continue to use GRUB without interruption.
+
+GRUB needs to be configured with the chainloader module to load Sprout.
+
+### x86_64
+
+```bash
+# Install x86_64 GRUB modules.
+$ sudo dnf install grub2-efi-x64-modules
+# Copy x86_64 GRUB modules to /boot/grub2 for use by GRUB if it isn't installed already.
+$ [ ! -d /boot/grub2/x86_64-efi ] && sudo cp -r /usr/lib/grub/x86_64-efi /boot/grub2/x86_64-efi
+```
+
+### ARM64
+
+```bash
+# Install ARM64 GRUB modules.
+$ sudo dnf install grub2-efi-aa64-modules
+# Copy ARM64 GRUB modules to /boot/grub2 for use by GRUB if it isn't installed already.
+$ [ ! -d /boot/grub2/arm64-efi ] && sudo cp -r /usr/lib/grub/arm64-efi /boot/grub2/x86_64-efi
+```
+
+You will need to find the UUID of your EFI System Partition. You can do this by running the following command:
+```bash
+$ grep "/boot/efi" /etc/fstab | awk '{print $1}' | awk -F '=' '{print $2}'
+SAMPLE-VALUE
+```
+
+The GRUB configuration for Sprout is as follows, replace `SAMPLE-VALUE` with the UUID of your EFI System Partition:
+
+```grub
+menuentry 'Sprout' $menuentry_id_option 'sprout' {
+        insmod part_gpt
+        insmod fat
+        insmod chain
+        search --no-floppy --fs-uuid --set=root SAMPLE-VALUE
+        chainloader /EFI/BOOT/sprout.efi
+}
+```
+
+You can append this to `/etc/grub.d/40_custom` and run the following command to update your configuration:
+```bash
+$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
+```
+
+To update your GRUB configuration.
+
+Make sure to update your GRUB environment to show the menu:
+
+```bash
+$ sudo grub2-editenv - set menu_auto_hide=0
+```
+
+You may now reboot your system and select Sprout from the GRUB menu.
+
+## Step 3, Option 2: Configure your EFI firmware for Sprout
+
+You can configure your EFI boot menu to show Sprout as an option.
+
+To do so, please find the partition device of your EFI System Partition and run the following:
+
+```bash
+$ sudo efibootmgr -d /dev/esp_partition_here -C -L 'Sprout' -l '\EFI\BOOT\sprout.efi'
+```
+
+This will add a new entry to your EFI boot menu called `Sprout` that will boot Sprout with your configuration.
+
+Now if you boot into your UEFI firmware, you should see Sprout as an option to boot.
