 The Memfault module provides an integration of `Memfault SDK`_ into |NCS| and expands the functionality of the SDK with some options that are specific to |NCS|.
-
-Overview
-********
+To get started with Memfault integration in |NCS|, see :ref:`ug_memfault`.
 
 `Memfault SDK`_ is an SDK for embedded devices to make use of services that `Memfault`_ offers on their platform.
-
-The SDK provides a functionality to collect debug information from devices in the form of coredumps, error traces, metrics, logs and more.
-Information that is collected from the device can be sent to Memfault's cloud solution for further analysis.
-Communication with the Memfault Cloud is handled by APIs available in Memfault SDK, while the integration code of the SDK in |NCS| provides some additional functionality.
-
 For official documentation for Memfault SDK and the Memfault platform in general, see `Memfault Docs`_.
 
-See the following examples of Memfault implementation in |NCS|:
-
-   * :ref:`memfault_sample` - This sample connects to the LTE network and sends data using HTTPS.
-     It supports nRF9160-based build targets
-   * :ref:`peripheral_mds` - This sample has an implementation of the MDS.
-     It sends data to the Memfault cloud through a Bluetooth gateway.

-Using Memfault SDK
-******************
-
-The SDK is part of the West manifest in |NCS| and is automatically downloaded when running ``west update``.
-By default, it is downloaded to ``<nRF Connect SDK path>/modules/lib/memfault-firmware-sdk/``.
-
-To include Memfault in your build, enable the Kconfig option :kconfig:option:`CONFIG_MEMFAULT`.
-The APIs in Memfault SDK can then be linked into your application.
-
-In addition, you must configure a Memfault project key using :kconfig:option:`CONFIG_MEMFAULT_NCS_PROJECT_KEY`.
-:kconfig:option:`CONFIG_MEMFAULT_NCS_PROJECT_KEY` is located in :file:`../overlay-memfault.conf`.
-
-To get access to all the benefits, like up to 100 free devices connected, register at the `Memfault registration page`_.
-
 .. note::
    When building applications with :ref:`Trusted Firmware-M <ug_tfm>` (TF-M), the faults resulting from memory access in secure regions are not caught by Memfault's fault handler.
    Instead, they are handled by TF-M.
