+## Supported platforms
+
+Mongoose can work on top of any TCP/IP stack that supports BSD sockets API.
+Platforms supported by the 3rd party TCP/IP stacks:
+
+| TCP/IP stack    | Notes |
+| --------------- | -------- |
+| **lwIP**            | All devices running lwIP, for example ESP32, ESP32S3, ESP32C3, ESP32C6, etc |
+| **Zephyr**          | All devices supported by Zephyr |
+| **Other**           | Any other TCP/IP stack that supports BSD socket API, for example Amazon FreeRTOS-TCP |
+| **Linux, Mac, Windows**   | Workstations, server, single board computers, embedded Linux devices running on MPUs or FPGAs |
+
+Optionally, Mongoose provides its own built-in TCP/IP stack, eliminating the
+need for additional software to implement networking functionality. The
+built-in stack supports operation in both bare-metal and RTOS environments.
+Platforms supported by the Mongoose built-in TCP/IP stack:
+
+| Hardware    | Notes |
+| ----------- | -------- |
+| **STM32** | All STM32 MCUs with built-in Ethernet: STM32Fxx, STM32H5xx, STM32H7xx |
+| **NXP**  |  All NXP MCUs with built-in Ethernet: IMXRT102x, IMXRT104x, IMXRT105x, IMXRT106x, IMXRT117x, RW612, MCXN94x   |
+| **Microchip**  | ATSAME54 MCUs with built-int Ethernet  |
+| **Renesas** | RA5M, RA6M, RA8M MCUs with built-in Ethernet    |
+| **Infineon**  | XMC4, XMC7 MCUs with built-in Ethernet    |
+| **Texas Instruments**  |  TM4C, TMS570 MCUs with built-in Ethernet   |
+| **Cypress WiFi**  | Any MCU with CY43xx WiFi chips, like RP2040 Pico-W, RP2350 Pico2-W, Arduino Portenta    |
+| **Wiznet Ethernet**  | Any MCU that use Wiznet W5500 or Wiznet 5100 MAC+PHY chips    |
+| **Cellular**  | NRF9160, SIM800    |
