+## 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    |

-## Contributing

-Rules for creating a new example:
-
-- Makefile golden reference for desktop/server example: [http-server](http-server)
-- Makefile golden reference for the embedded example:
-   [stm32/nucleo-f746zg-baremetal](stm32/nucleo-f746zg-baremetal)
-- An example must build on Windows, Mac and Ubuntu Linux systems
-- Assume that user installed tools according to https://mongoose.ws/tutorials/tools/
-- Makefile must not include any other make files
-- Use `CFLAGS` for system-specific compilation options
-- Use `CFLAGS_MONGOOSE` for mongoose-specific compilation options
-- Use `$(CFLAGS) $(CFLAGS_MONGOOSE) $(CFLAGS_EXTRA)` to compile
-- If external repository is required, download it on demand using git
-  shallow clone. See embedded example golden reference
-- Keep Makefile as short as possible, but verbose to understand it easily
-- Symlink files when required, like `mongoose.c`, `ca.pem`, etc. Make no copies
-- Example's README.md should contain only the title and the link to mongoose.ws

-# Mongoose as a MicroPython user module on the ESP32
-
-The most basic usage is:
-
-```python
-import network
-import mongoose
-
-sta_if = network.WLAN(network.STA_IF)
-sta_if.active(True)                      
-sta_if.connect("<SSID>", "<PASSWORD>")
-while not sta_if.isconnected():
-    pass
-
-mongoose.init()
-while True:
-    mongoose.poll(1000)
-
-```
-
-Check [_thread](https://docs.micropython.org/en/latest/library/_thread.html) support for more advanced usage

-# Mongoose as a MicroPython user module
-
-The most basic usage is in `main.py`.
-
-You'll have to configure Mongoose for your desired platform, this example runs on the `unix` port and Mongoose detects it as a known architecture and hence configures itself to use sockets and time base. For other platforms, you'll have to do your homework (there's plenty of Mongoose examples for several platforms); also check respective MicroPython build instructions.
-
-Check [_thread](https://docs.micropython.org/en/latest/library/_thread.html) support for more advanced usage
