+Overview
+********
+
+:ref:`npmx-zephyr <index>` provides an example of `npmx library`_ integration with the `Zephyr`_ RTOS environment.
+This can be used as a starting point for an integration with other RTOS or bare-metal environments.
+
+For the user's convenience, this repository includes also a variety of sample applications demonstrating how to use the `npmx drivers`_.
+Their code is available on the GitHub `npmx-zephyr repository`_.

+The following matrix provides a comparative overview of which drivers are supported by specific Nordic nPMs.

+
+How to use
+**********
+
+Repository initialization
+=========================
+
+The recommended way to clone the repositories is by using the ``west`` tool.
+Information about the installation, available commands, configuration and more can be found in the `Zephyr's west`_ tool documentation.
+
+To initalize the npmx-zephyr repository, run the following commands:
+
+.. code:: bash
+
+   mkdir <new_directory>
+   cd <new_directory>
+   west init -m https://github.com/NordicSemiconductor/npmx-zephyr
+   cd npmx-zephyr
+   west update
+
+Alternatively, you can clone repositories by using git only.
+In this case pay special attention to revisions - both Zephyr and npmx revisions should match the ones specified in the ``west.yml``.
+Moreover, the ``npmx`` folder should be placed in the ``zephyr/modules`` subdirectory.
+
+Building and running sample application
+=======================================
+
+To run one of the :doc:`sample applications <samples>`, do the following:
+
+* Configure the setup based on the relevant sample documentation.
+* Build and flash the application to the target device by using the following commands:
+
+  .. code:: bash
+
+     cd <path_to_npmx-zephyr>/samples/<desired_sample>
+     west build -b <target>
+     west flash
+
+For instance, if you want to run the LED sample for nPM1300 Engineering B used with nRF52840DK, you must configure the setup as specified in the :doc:`LED sample <../samples/led/README>` description.
+After that, run the following commands:
+
+.. code:: bash
+
+   cd npmx-zephyr/samples/led
+   west build -b nrf52840dk_nrf52840
+   west flash
+
+As a result, you should see LEDs blinking on the board.
+
+.. note::
+   Make sure that the ``ZEPHYR_BASE`` variable is set as a path to your Zephyr folder (the one you have cloned with west).
+
+   If not, set this variable manually with the following command:
+
+   .. code:: bash
+
+      export ZEPHYR_BASE=<path_to_zephyr_directory>
+
+Generating documentation
+========================
+
+All files that are required to compile the Sphinx-based documentation for the ``npmx-zephyr`` repository are located under the ``doc`` folder.
+
+Requirements
+------------
+
+Install Python 3 and its dependencies with the following command:
+
+.. code:: bash
+
+   pip install -r scripts/requirements.txt
+
+Build
+-----
+
+You can build the documentation in two ways:
+
+* Use the provided script ``doc/sphinx_build_local.sh`` and open the ``doc/build/html/index.html`` file to see the output.
+* Build it manually by going to the ``doc`` directory and running the following command:
+
+  .. code:: bash
+
+     sphinx-build -M html . build
