+designed with support for the modern `Swift language
+`_. Zephyr provides basic
+low-level capabilities for the SwiftIO Feather board. Swift application would
+run on top of Zephyr. More information about the board can be found
+at:
+
+- `MadMachine Homepage`_

+
+Programming and Flash
+*************************
+
+Build and flash applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+Configuring a Console
+=====================
+
+Connect a USB-to-serial adapter from your PC to corresponding UART pins of SwiftIO Feather.
+
+Use the following settings with your serial terminal of choice (minicom, putty,
+etc.):
+
+- Speed: 115200
+- Data: 8 bits
+- Parity: None
+- Stop bits: 1
+
+Flashing
+========
+
+Here is an example for the :ref:`hello_world` application.
+
+Connect a DAPLink debuger from your PC to corresponding SWD pins of SwiftIO Feather.
+
+.. zephyr-app-commands::
+ :zephyr-app: samples/hello_world
+ :board: mm_feather
+ :goals: flash
+
+Open a serial terminal, reset the board (press the "reset" button), and you should
+see the following message in the terminal:
+
+.. code-block:: console
+
+ *** Booting Zephyr OS build v2.6.0-rc1-301-gd9c666a5abf8 ***
+ Hello World! mm_feather
+
+Debugging
+=========
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+ :zephyr-app: samples/hello_world
+ :board: mm_feather
+ :goals: debug
+
+Open a serial terminal, step through the application in your debugger, and you
+should see the following message in the terminal:
+
+.. code-block:: console
+
+ *** Booting Zephyr OS build v2.6.0-rc1-301-gd9c666a5abf8 ***
+ Hello World! mm_feather
