+MCUboot bootloader
+==================
+
+The sysbuild makes possible to build and flash all necessary images needed to
+bootstrap the board.
+
+To build the sample application using sysbuild use the command:
+
+.. zephyr-app-commands::
+   :tool: west
+   :zephyr-app: samples/hello_world
+   :board: ek_ra8p1/r7ka8p1kflcac/cm85
+   :goals: build flash
+   :west-args: --sysbuild
+   :gen-args: -DSB_CONFIG_BOOTLOADER_MCUBOOT=y
+
+By default, Sysbuild creates MCUboot and user application images.
+
+Build directory structure created by sysbuild is different from traditional
+Zephyr build. Output is structured by the domain subdirectories:
+
+.. code-block::
+
+  build/
+  ├── hello_world
+  |    └── zephyr
+  │       ├── zephyr.elf
+  │       ├── zephyr.hex
+  │       ├── zephyr.bin
+  │       ├── zephyr.signed.bin

+  │       ├── zephyr.elf
+  │       ├── zephyr.hex
+  │       └── zephyr.bin
+  └── domains.yaml
+
+.. note::
+
+   With ``--sysbuild`` option, MCUboot will be rebuilt and re-flashed
+   every time the pristine build is used.
+
+To only flash the user application in the subsequent builds, Use:
+
+.. code-block:: console
+
+   $ west flash --domain hello_world
+
+For more information about the system build please read the :ref:`sysbuild` documentation.
