+
+## Hardware Configuration Matrix
+
+Generally, the same [hardware configuration](hardware-matrix.md) as for the
+UEFI variant applies.
+
+A notable addition is usage of the
+[Nitrokey 3A Mini](https://novacustom.com/product/nitrokey-3a-mini/)
+USB device, which is required for Heads installation and usage.
+
+## Test Matrix
+
+Please refer to the [tests results spreadsheet](https://docs.google.com/spreadsheets/d/1yWZ--zFPIsQhXZByf7nJIrasQYuRSf1yCi60lY_RGsQ).
+
+## Building manual
+
+This section presents the crucial steps required to build the Dasharo Heads
+firmware. For more information, you may also refer to the official
+[Heads building documentation](https://osresearch.net/general-building/).
+
+### Requirements
+
+This guide was verified on Ubuntu 22.04. In practice, any Linux distribution
+with [Docker](https://www.docker.com/) support should be enough to complete it.
+
+Make sure that you have following packages installed:
+
+- Docker
+ + follow [Install Docker Engine on Ubuntu](https://docs.docker.com/engine/install/ubuntu/)
+ + follow [Post-installation steps for Linux](https://docs.docker.com/engine/install/linux-postinstall/)
+- Git
+
+ ```bash
+ sudo apt -y install git
+ ```
+
+### Building
+
+1. Clone Dasharo Heads repository:
+
+ ```bash
+ git clone https://github.com/Dasharo/heads.git
+ ```
+
+1. Navigate to the source code directory and checkout to the desired revision:
+
+ ```bash
+ cd heads
+ git checkout novacustom_nv4x_adl_v0.9.0
+ ```
+
+1. Start the build inside the docker container:
+
+ ```bash
+ docker run --rm -it -v $PWD:$PWD -w $PWD \
+ 3mdeb/heads-docker:3.0.1 make BOARD=nitropad-nv41
+ ```
+
+This will produce a Dasharo binary placed in
+`build/x86/nitropad-nv41/dasharo-nitropad-nv41-*.rom`.
+
+## Switching from Dasharo UEFI to Heads
+
+To change firmware branches from UEFI to Heads, because of how different the two
+firmware types are, it's required to disable some security measures before
+flashing. Follow the steps below to install Heads from an existing Dasharo UEFI
+firmware installation:
+
+- Hold down the ++f2++ key and press the ++power++ button to enter the UEFI
+ Setup Menu
+- Enter the `Device Manager` submenu and disable `Secure Boot`
+- Enter the `Dasharo System Features` submenu
+- In the `Dasharo Security Options` submenu, disable:
+ + SMM BIOS Write Protection
+ + BIOS boot medium lock
+- In the `Intel Management Engine Options` submenu disable the Management Engine
+
+!!! tip
+
+ For a more detailed guide on the UEFI Setup Menu options, check out the
+ [Dasharo menu documentation](https://docs.dasharo.com/dasharo-menu-docs/).
+
+- [Boot into Dasharo Tools Suite](https://docs.dasharo.com/dasharo-tools-suite/documentation/#running)
+- Enter your DES subscription credentials
+- Select `Update Dasharo firmware` to check for updates
+- When asked to switch to Heads firmware, press `Y`
+- Proceed with [DTS firmware update](https://docs.dasharo.com/dasharo-tools-suite/documentation/#firmware-update)
+ as usual
+
+When the update is finished, your laptop will shut down automatically. Power it
+back on to boot into your new Heads installation!
+
+!!! warning "TOTP secrets warning"
+
+ On the first boot, you will be shown a warning about TOTP secrets. This is
+ normal and expected on the first boot. Run `OEM Factory Reset /
+ Re-Ownership` to finish deploying Heads.
+
+ Check out [Heads documentation](https://osresearch.net/Configuring-Keys/#oem-factory-resetre-ownership)
+ for a detailed factory reset guide.
+
+!!! note "Note for Qubes OS users"
+
+ After installing Qubes while Heads is installed, you will need to select
+ `Reset TPM` in the Heads menu to finish the installation.
+
+ From the main menu, enter `Options` -> `TPM/TOTP/HOTP Options` and select
+ `Reset the TPM`.
+
+ Users upgrading to Heads while Qubes is already installed are not affected.
+
+## Switching from Dasharo Heads back to UEFI
+
+To revert back to UEFI, you will need to boot into DTS from a USB stick.
+
+- Follow the [Dasharo Tools Suite documentation](https://docs.dasharo.com/dasharo-tools-suite/documentation/#running)
+ to boot DTS from a USB stick
+- In the DTS main menu, select `Update Dasharo firmware` to check for available
+ updates.
+- When prompted to revert back to UEFI, press `Y`
+- Proceed with [DTS firmware update](https://docs.dasharo.com/dasharo-tools-suite/documentation/#firmware-update)
+ as usual
+
+Once finished, your laptop will shut down automatically. Power it back on to
+boot into your UEFI firmware.
+
+> When reverting to UEFI, it's not possible to restore EFI boot manager entries
+> that were added before installing Heads. Therefore, you may need to re-create
+> your boot entries manually, or find your boot loader using `Boot From File`
+> option in the UEFI setup menu.
+
+## Logo customization
+
+To replace the logo, one must rebuild the firmware. Other methods are not
+supported as of now. You would need to replace the
+`branding/Dasharo/bootsplash.jpg` with your own, and proceed with the
+[Building manual](#building-manual).
+
+## Initial deployment
+
+The supported method is to follow the
+[initial deployment](/unified/novacustom/initial-deployment.md), and then the
+[Transition from Dasharo UEFI to Heads variant](#switching-from-dasharo-uefi-to-heads).
+
+## Firmware update
+
+[Build](#building-manual) or download Dasharo Heads firmware, and proceed with
+the official [Heads update documentation](https://osresearch.net/Updating).
