+Start Application Development
+*****************************
+
+Before powering up your M5StickC PLUS, please make sure that the board is in good
+condition with no obvious signs of damage.
+
+System requirements
+===================
+
+Prerequisites
+-------------
+
+Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command
+below to retrieve those files.
+
+.. code-block:: console
+
+   west blobs fetch hal_espressif
+
+.. note::
+
+   It is recommended running the command above after :file:`west update`.
+
+Building & Flashing
+*******************
+
+.. zephyr:board-supported-runners::
+
+Simple boot
+===========
+
+The board could be loaded using the single binary image, without 2nd stage bootloader.
+It is the default option when building the application without additional configuration.
+
+.. note::
+
+   Simple boot does not provide any security features nor OTA updates.
+
+MCUboot bootloader
+==================
+
+User may choose to use MCUboot bootloader instead. In that case the bootloader
+must be built (and flashed) at least once.
+
+There are two options to be used when building an application:
+
+1. Sysbuild
+2. Manual build
+
+.. note::
+
+   User can select the MCUboot bootloader by adding the following line
+   to the board default configuration file.
+
+   .. code:: cfg
+
+      CONFIG_BOOTLOADER_MCUBOOT=y
+
+Sysbuild
+========
+
+The sysbuild makes possible to build and flash all necessary images needed to
+bootstrap the board with the ESP32 SoC.
+
+To build the sample application using sysbuild use the command:
+
+.. zephyr-app-commands::
+   :tool: west
+   :zephyr-app: samples/hello_world
+   :board: m5stickc_plus2
+   :goals: build
+   :west-args: --sysbuild
+   :compact:
+
+By default, the ESP32 sysbuild creates bootloader (MCUboot) and application
+images. But it can be configured to create other kind of 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.bin
+  ├── mcuboot
+  │    └── zephyr
+  │       ├── zephyr.elf
+  │       └── zephyr.bin
+  └── domains.yaml
+
+.. note::
+
+   With ``--sysbuild`` option the bootloader will be re-build and re-flash
+   every time the pristine build is used.
+
+For more information about the system build please read the :ref:`sysbuild` documentation.
+
+Manual build
+============
+
+During the development cycle, it is intended to build & flash as quickly possible.
+For that reason, images can be built one at a time using traditional build.
+
+The instructions following are relevant for both manual build and sysbuild.
+The only difference is the structure of the build directory.
+
+.. note::
+
+   Remember that bootloader (MCUboot) needs to be flash at least once.
+
+Build and flash applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: m5stickc_plus2/esp32/procpu
+   :goals: build
+
+The usual ``flash`` target will work with the ``m5stickc_plus2`` board
+configuration. Here is an example for the :zephyr:code-sample:`hello_world`
+application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: m5stickc_plus2/esp32/procpu
+   :goals: flash
+
+The default baud rate for the M5StickC PLUS is set to 1500000bps. If experiencing issues when flashing,
+try using different values by using ``--esp-baud-rate <BAUD>`` option during
+``west flash`` (e.g. ``west flash --esp-baud-rate 115200``).
+
+You can also open the serial monitor using the following command:
+
+.. code-block:: shell
+
+   west espressif monitor
+
+After the board has automatically reset and booted, you should see the following
+message in the monitor:
+
+.. code-block:: console
+
+   ***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx *****
+   Hello World! m5stickc_plus2
+
+Debugging
+*********
+
+M5StickC PLUS debugging is not supported due to pinout limitations.
