+Introduction
+************
+
+nPM1300 is a Power Management IC (PMIC) with a linear-mode lithium-ion, lithium-polymer, and lithium ferro-phosphate battery charger.
+It has two dual-mode buck regulators, two dual purpose LDO/load switches, three LED drivers and five GPIOs.
+
+nPM1300 is the perfect companion for nRF52 and nRF53 Series SoCs, and the nRF91 series SiP.
+It is ideal for compact and advanced IoT products such as wearables and portable medical applications.
+
+For additional information, see the following documentation:
+
+* `nPM1300`_ for the technical documentation on the nPM1300 PMIC and associated kits.
+* :ref:`ug_npm1300_gs`.
+* The :ref:`introductory documentation <getting_started>` if you are not familiar with the |NCS| and the development environment.
+
+Supported boards

+
+This section gets you started with your nPM1300 :term:`Evaluation Kit (EK)` using the |NCS|.
+It tells you how to build and flash the :ref:`npm1300_fuel_gauge` sample and perform a quick test of your EK.
+
+If this is your first time developing with a Nordic DK, read the appropriate getting started tutorial first:
+
+* :ref:`ug_nrf52_gs`
+* :ref:`ug_nrf5340_gs`
+* :ref:`ug_nrf9160_gs`
+
+Minimum requirements
+********************
+
+Make sure you have all the required hardware and that your computer has one of the supported operating systems.
+
+Hardware
+========
+
+* One of the following development kits:
+
+  * nRF52 DK
+  * nRF52840 DK
+  * nRF5340 DK
+  * nRF9120 DK
+
+* nPM1300 EK
+* A suitable battery
+* Micro-USB 2.0 cable
+* USB-C charger
+* Jumper wires
+
+Software
+========
+
+On your computer, one of the following operating systems:
+

+
+Installing the required software
+********************************
+
+Install `nRF Connect for Desktop`_.
+After installing and starting the application, install the Programmer app.
+
+.. _npm1300_gs_building:
+
+Building and programming the sample
+***********************************
+
+Follow the detailed instructions in the :ref:`npm1300_fuel_gauge` sample documentation to build the sample and flash it to the DK.
+
+.. _npm1300_gs_testing:
+
+Testing the sample
+******************
+
+When the fuel gauge software has connected successfully to the PMIC on the EK, it will display the following status information:
+
+.. code-block:: console
+
+   PMIC device ok
+   V: 4.101, I: 0.000, T: 23.06, SoC: 93.09, TTE: nan, TTF: nan
+
+Next steps
+**********
+
+You have now completed getting started with the nPM1300 EK.
+See the following links for where to go next:
+
+* The EK `User Guide <nPM1300 EK User Guide_>`_ for detailed information related to the nPM1300 EK.
