+# Renesas Wi-SUN FAN CSMP Agent Integration
+
+<p align="left">
+  <img src="resources/renesas-logo.jpg" alt="Renesas logo" width="220">
+</p>
+
+## Summary
+
+The integration targets Renesas Wi-SUN FAN products based on the Renesas RX MCU family.
+Renesas provides Wi-SUN FAN-compliant Sub-GHz solutions for Wi-SUN FAN applications.
+For the list of officially supported devices, stack versions, configuration options, and available features, please refer to the Renesas Wi-SUN FAN product and software documentation.
+
+The purpose of this integration is to enable a Renesas Wi-SUN FAN node to communicate with Cisco Field Network Director (FND) using CSMP.
+It provides platform-specific functionality required by the CSMP Agent Library, including:
+
+- UDP/IPv6 communication over the Renesas Wi-SUN FAN protocol stack,
+- access to platform, stack, and firmware information,
+- mapping of Wi-SUN FAN network and firmware information to CSMP TLV objects,
+- firmware update integration.
+
+## Requirements
+
+The following components are required to build and run the Renesas Wi-SUN FAN CSMP Agent integration:
+
+- A running instance of Cisco Field Network Director (FND). For a development setup, please refer to the [CSMP Developer Tutorial](../../docs/CSMP%20Developer%20Tutorial%20-%200v11.pdf).
+
+- At least two [Renesas Wi-SUN FAN Development Kits](https://www.renesas.com/en/design-resources/boards-kits/rtk0ee0013d10002bj).
+
+- The latest Renesas [Wi-SUN FAN Protocol Stack](https://www.renesas.com/en/software-tool/sub-ghzwi-sun-protocol-stack).
+
+## Renesas Wi-SUN FAN Stack
+
+This Renesas CSMP integration layer is designed to be used in conjunction with the latest version of the [Renesas Wi-SUN FAN Protocol Stack](https://www.renesas.com/en/software-tool/sub-ghzwi-sun-protocol-stack).
+Different versions may not work, so please make sure that this CSMP integration layer is used with the correct version of the Renesas Wi-SUN FAN Protocol Stack!
+
+Further information about the CSMP usage with the Renesas Wi-SUN FAN protocol stack, APIs, configuration, sample applications, and supported platforms is provided in the user manual of the Renesas Wi-SUN FAN Protocol Stack and accompanying documentation, which are located in the release package of the Renesas Wi-SUN FAN Protocol Stack.
+It also includes instructions for configuring and running a sample setup for CSMP with Renesas Wi-SUN FAN nodes.
