 ## Development Setup

 You can use any Rust development environment to develop Sprout.
-
 Rustup is recommended as the Rust toolchain manager to manage Rust versions and targets.
-
-Sprout currently requires Rust nightly to support uefi_std. See [uefi_std](https://doc.rust-lang.org/beta/rustc/platform-support/unknown-uefi.html) for more details.
-
 We currently only support `x86_64-unknown-uefi` and `aarch64-unknown-uefi` targets.

 To test your changes in QEMU, please run `./hack/dev/boot.sh`, you can specify `x86_64` or `aarch64`
 as an argument to boot.sh to boot the specified architecture.

+## Crate Structure
+
+Sprout is split into multiple crates:
+
+- `edera-sprout-boot` as `crates/boot`: Bootloader entrypoint for Sprout.
+- `edera-sprout-build` at `crates/build`: Build logic for Sprout.
+- `edera-sprout-config` at `crates/config`: Serialization structures for the Sprout configuration file.
+- `edera-sprout-eficore` at `crates/eficore`: Core library for Sprout EFI code.
+
+It is intended that overtime Sprout will be split into even more crates.
+
 ## Hack Scripts

 You can use the `./hack` scripts to run common development tasks:

+# Setup Sprout for Fedora with Secure Boot
+
+## Prerequisites
+
+- Modern Fedora release: tested on Fedora 43 x86_64.
+- EFI System Partition mounted on `/boot/efi` (the default)
+- You will need the following packages installed: `openssl`, `mokutil`, `sbsigntools`, `efibootmgr`
+
+**NOTE**: Fedora on ARM64 itself does not support Secure Boot consistently.
+
+## Step 1: Generate and Install Secure Boot Key
+
+```bash
+# Create a directory to store the Secure Boot MOK key and certificates.
+$ mkdir -p /etc/sprout/secure-boot
+# Change to the created directory.
+$ cd /etc/sprout/secure-boot
+# Generate a MOK key and certificate.
+$ openssl req \
+    -newkey rsa:4096 -nodes -keyout mok.key \
+    -new -x509 -sha256 -days 3650 -subj '/CN=Sprout Secure Boot/' \
+    -out mok.crt
+# Generate a DER encoded certificate for enrollment.
+$ openssl x509 -outform DER -in mok.crt -out mok.cer
+# Import the certificate into the Secure Boot environment.
+# This will ask you to make a password that will be used during enrollment.
+$ mokutil --import mok.cer
+# Reboot your machine.
+# During boot, MOK enrollment should appear. If it doesn't, ensure you are booting into the shim.
+# Press any key to begin MOK management. Select "Enroll MOK".
+# Select "View key 0", and ensure the subject says "CN=Sprout Secure Boot".
+# If the subject does not match, something has gone wrong with MOK enrollment.
+# Press Enter to continue, then select the "Continue" option.
+# When it asks to enroll the key, select the "Yes" option.
+# Enter the password that you created during the mokutil --import step.
+# Select "Reboot" to boot back into your Operating System.
+```
+
+## Step 2: Prepare the Secure Boot Environment
+
+```bash
+# Create a directory for Sprout EFI artifacts.
+$ mkdir -p /boot/efi/EFI/sprout
+
+# For x86_64, copy the following artifacts to the Sprout EFI directory.
+$ cp /boot/efi/EFI/fedora/shimx64.efi /boot/efi/EFI/sprout/shimx64.efi
+$ cp /boot/efi/EFI/fedora/mmx64.efi /boot/efi/EFI/sprout/mmx64.efi
+
+# For aarch64, copy the following artifacts to the Sprout EFI directory.
+$ cp /boot/efi/EFI/fedora/shimaa64.efi /boot/efi/EFI/sprout/shimaa64.efi
+$ cp /boot/efi/EFI/fedora/mmaa64.efi /boot/efi/EFI/sprout/mmaa64.efi
+```
+
+## Step 3: Install Unsigned Sprout
+
+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 ARM64 systems, download the `sprout-aarch64.efi` file.
+Copy the downloaded `sprout.efi` file to `/boot/efi/EFI/sprout/sprout.unsigned.efi` on your EFI System Partition.
+
+## Step 4: Sign Sprout for Secure Boot
+
+```bash
+# For x86_64, sign the unsigned Sprout artifact and name it grubx64.efi which is what the shim will call.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/grubx64.efi \
+    /boot/efi/EFI/sprout/sprout.unsigned.efi
+
+# For aarch64, sign the unsigned Sprout artifact and name it grubaa64.efi which is what the shim will call.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/grubaa64.efi \
+    /boot/efi/EFI/sprout/sprout.unsigned.efi
+```
+
+## Step 5: Install and Sign EFI Drivers
+
+You will need a filesystem EFI driver if `/boot` is not FAT32 or ExFAT.
+
+### ext4
+
+Most Fedora systems use an ext4 filesystem for `/boot`, if that is the case, use the ext4 instructions here:
+
+Install the necessary `edk2-ext4` package:
+
+```bash
+# Install the ext4 driver from the package manager.
+$ dnf install edk2-ext4
+```
+
+Copy the ext4 driver to `/boot/efi/EFI/sprout/ext4.unsigned.efi`:
+
+```bash
+# For x86_64, copy the ext4x64.efi driver to the Sprout EFI directory.
+$ cp /usr/share/edk2/drivers/ext4x64.efi /boot/efi/EFI/sprout/ext4.unsigned.efi
+
+# For aarch64, copy the ext4aa64.efi driver to the Sprout EFI directory.
+$ cp /usr/share/edk2/drivers/ext4aa64.efi /boot/efi/EFI/sprout/ext4.unsigned.efi
+```
+
+```bash
+# Sign the ext4 driver at ext4.unsigned.efi, placing it at ext4.efi, which will be used in the configuration.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/ext4.efi \
+    /boot/efi/EFI/sprout/ext4.unsigned.efi
+```
+
+### Other Filesystems
+
+If you need another driver, you can download EFI filesystem drivers from [EfiFs releases](https://github.com/pbatard/EfiFs/releases).
+Copy the driver to `/boot/efi/EFI/sprout/DRIVER_NAME.unsigned.efi` for signing, then sign it like this:
+
+```bash
+# Sign your driver, placing it at DRIVER_NAME.efi, which will be used in the configuration.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/DRIVER_NAME.efi \
+    /boot/efi/EFI/sprout/DRIVER_NAME.unsigned.efi
+```
+
+You will add the driver in your Sprout configuration below, like this:
+
+```toml
+[drivers.DRIVER_NAME]
+path = "\\EFI\\sprout\\DRIVER_NAME.efi"
+```
+
+## Step 6: Create Sprout Configuration
+
+Write the following to the file `/boot/efi/sprout.toml`:
+
+```toml
+# sprout configuration: version 1
+version = 1
+
+# load an ext4 EFI driver.
+# skip this if you do not have a filesystem driver.
+# if your filesystem driver is not named ext4, change accordingly.
+[drivers.ext4]
+path = "\\EFI\\sprout\\ext4.efi"
+
+# global options.
+[options]
+# enable autoconfiguration by detecting bls enabled
+# filesystems and generating boot entries for them.
+autoconfigure = true
+```
+
+Ensure you add the signed driver paths to the configuration, not the unsigned ones.
+If you do not have any drivers, exclude the drivers section entirely.
+
+## Step 7: Configure Sprout Boot Entry
+
+In the following commands, replace /dev/BLOCK_DEVICE with the device that houses your GPT partition table,
+and PARTITION_NUMBER with the partition number of the EFI System Partition. For example, if your EFI System Partition is
+`/dev/sda1`, the BLOCK_DEVICE would be `/dev/sda` and the PARTITION_NUMBER would be `1`
+
+```bash
+# For x86_64, run this command to add Sprout as the default boot entry.
+$ efibootmgr -d /dev/BLOCK_DEVICE -p PARTITION_NUMBER -c -L 'Sprout' -l '\EFI\sprout\shimx64.efi'

+# Setup Sprout for openSUSE with Secure Boot
+
+**NOTE:** This guide may not function as written if the system validates hashes.
+If your system validates hashes in the shim, you will need to use MokManager to enroll the hashes
+of every EFI file involved, such as Sprout and any EFI drivers.
+
+## Prerequisites
+
+- Modern openSUSE release: tested on openSUSE Tumbleweed ARM64
+- EFI System Partition mounted on `/boot/efi` (the default)
+- You will need the following packages installed: `openssl`, `shim`, `mokutil`, `sbsigntools`
+
+## Step 1: Generate and Install Secure Boot Key
+
+```bash
+# Create a directory to store the Secure Boot MOK key and certificates.
+$ mkdir -p /etc/sprout/secure-boot
+# Change to the created directory.
+$ cd /etc/sprout/secure-boot
+# Generate a MOK key and certificate.
+$ openssl req \
+    -newkey rsa:4096 -nodes -keyout mok.key \
+    -new -x509 -sha256 -days 3650 -subj '/CN=Sprout Secure Boot/' \
+    -out mok.crt
+# Generate a DER encoded certificate for enrollment.
+$ openssl x509 -outform DER -in mok.crt -out mok.cer
+# Import the certificate into the Secure Boot environment.
+# This will ask you to make a password that will be used during enrollment.
+$ mokutil --import mok.cer
+# Reboot your machine.
+# During boot, MOK enrollment should appear. If it doesn't, ensure you are booting into the shim.
+# Press any key to begin MOK management. Select "Enroll MOK".
+# Select "View key 0", and ensure the subject says "CN=Sprout Secure Boot".
+# If the subject does not match, something has gone wrong with MOK enrollment.
+# Press Enter to continue, then select the "Continue" option.
+# When it asks to enroll the key, select the "Yes" option.
+# Enter the password that you created during the mokutil --import step.
+# Select "Reboot" to boot back into your Operating System.
+```
+
+## Step 2: Prepare the Secure Boot Environment
+
+```bash
+# Create a directory for Sprout EFI artifacts.
+$ mkdir -p /boot/efi/EFI/sprout
+
+# For x86_64, copy the following artifacts to the Sprout EFI directory.
+$ cp /usr/share/efi/x86_64/shim.efi /boot/efi/EFI/sprout/shim.efi
+$ cp /usr/share/efi/x86_64/MokManager.efi /boot/efi/EFI/sprout/MokManager.efi
+$ cp /usr/share/efi/x86_64/fallback.efi /boot/efi/EFI/sprout/fallback.efi
+
+# For aarch64, copy the following artifacts to the Sprout EFI directory.
+$ cp /usr/share/efi/aarch64/shim.efi /boot/efi/EFI/sprout/shim.efi
+$ cp /usr/share/efi/aarch64/MokManager.efi /boot/efi/EFI/sprout/MokManager.efi
+$ cp /usr/share/efi/aarch64/fallback.efi /boot/efi/EFI/sprout/fallback.efi
+```
+
+## Step 3: Install Unsigned Sprout
+
+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 ARM64 systems, download the `sprout-aarch64.efi`
+file.
+Copy the downloaded `sprout.efi` file to `/boot/efi/EFI/sprout/sprout.unsigned.efi` on your EFI System Partition.
+
+## Step 4: Sign Sprout for Secure Boot
+
+```bash
+# Sign the unsigned Sprout artifact and name it grub.efi which is what the shim will call.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/grub.efi \
+    /boot/efi/EFI/sprout/sprout.unsigned.efi
+```
+
+## Step 5: Install and Sign EFI Drivers
+
+You will need a filesystem EFI driver if `/boot` is not FAT32 or ExFAT.
+If `/boot` is FAT32 or ExFAT, you can skip this step.
+
+Most Debian systems use an ext4 filesystem for `/boot`.
+You can download an EFI filesystem driver from [EfiFs releases](https://github.com/pbatard/EfiFs/releases).
+For ext4, download the `ext2` file for your platform. It should work for ext4 filesystems too.
+
+If you have an EFI driver, copy the driver to `/boot/efi/EFI/sprout/DRIVER_NAME.unsigned.efi` for signing.
+
+For example, the `ext4` driver, copy the `ext4.efi` file to `/boot/efi/EFI/sprout/ext4.unsigned.efi`.
+
+Then sign the driver with the Sprout Secure Boot key:
+
+```bash
+# Sign the ext4 driver at ext4.unsigned.efi, placing it at ext4.efi, which will be used in the configuration.
+$ sbsign \
+    --key /etc/sprout/secure-boot/mok.key \
+    --cert /etc/sprout/secure-boot/mok.crt \
+    --output /boot/efi/EFI/sprout/ext4.efi \
+    /boot/efi/EFI/sprout/ext4.unsigned.efi
+```
+
+## Step 6: Create Sprout Configuration
+
+Write the following to the file `/boot/efi/sprout.toml`:
+
+```toml
+# sprout configuration: version 1
+version = 1
+
+# global values.
+[values]
+# your linux kernel command line.
+linux-options = "root=UUID=MY_ROOT_UUID"
+
+# load an ext4 EFI driver.
+# skip this if you do not have a filesystem driver.
+# if your filesystem driver is not named ext4, change accordingly.
+[drivers.ext4]
+path = "\\EFI\\sprout\\ext4.efi"
+
+# global options.
+[options]
+# enable autoconfiguration by detecting bls enabled filesystems
+# or linux kernels and generating boot entries for them.
+autoconfigure = true
+```
+
+Ensure you add the signed driver paths to the configuration, not the unsigned ones.
+If you do not have any drivers, exclude the drivers section entirely.
+
+## Step 7: Configure Sprout Boot Entry
+
+In the following commands, replace /dev/BLOCK_DEVICE with the device that houses your GPT partition table,
+and PARTITION_NUMBER with the partition number of the EFI System Partition. For example, if your EFI System Partition is
+`/dev/sda1`, the BLOCK_DEVICE would be `/dev/sda` and the PARTITION_NUMBER would be `1`
+
+```bash
+# Run this command to add Sprout as the default boot entry.
+$ efibootmgr -d /dev/BLOCK_DEVICE -p PARTITION_NUMBER -c -L 'Sprout' -l '\EFI\sprout\shim.efi'
+```
+
+Reboot your machine and it should boot into Sprout.
+If Sprout fails to boot, it should boot into the original bootloader.
