+Programming and Debugging
+*************************
+
+Flashing
+========
+
+Build and flash applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+The easiest way to flash Zephyr onto a RuuviTag requires an external Ruuvi DEVKIT. More information about the board can be found at the
+`ruuvitag devkit`_.
+
+Once your tag is conencted to the DEVKIT and conencted to your PC, build and flash the application in the usual way.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: ruuvi_ruuvitag
+   :goals: build flash
+
+Advanced users may want to program the RuuviTag without the DEVKIT, this can be achieved via the SWDIO and SWDCLK pins located on the back of the RuuviTag.
+
+Debugging
+=========
+
+If using the Ruuvi DEVKIT refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
+Segger IC.
+
+Testing the LEDs and buttons on the RuuviTag
+********************************************
+
+There are 2 samples that allow you to test that the buttons (switches) and LEDs on
+the board are working properly with Zephyr:
+
+* :ref:`blinky-sample`
+* :ref:`button-sample`
+
+You can build and flash the examples to make sure Zephyr is running correctly on
+your board. The button and LED definitions can be found in :file:`boards/arm/ruuvi_ruuvitag/ruuvi_ruuvitag.dts`.
