+1. Python for NuttX runs on RISC-V QEMU (emulated) and on Espressif's ESP32-S3.
 2. Python modules are stored in `pyc <https://docs.python.org/3/glossary.html#term-bytecode>`_ (byte-code format) and are loaded from a ROMFS image at startup.
 3. The Python wrapper application on NuttX mounts the ROMFS partition which contains the Python modules and sets the required environment variables (``PYTHONHOME`` and ``PYTHON_BASIC_REPL``) automatically.

+ESP32-S3
+--------
+
+For this example, we will use the ESP32-S3 board. Use the ``esp32s3-devkit:python`` config to build
+Python for NuttX. Note that this defconfig uses a board with the ESP32-S3-WROOM-2 module with 32MiB
+of flash and 8MiB of PSRAM.
+
+Build and flash the ESP32-S3 board with the following commands:
+
+.. code:: console
+
+   $ cd nuttx
+   $ make distclean
+   $ ./tools/configure.sh esp32s3-devkit:python
+   $ make flash ESPTOOL_BINDIR=./ ESPTOOL_PORT=/dev/ttyUSB0 -s -j$(nproc)
+
+To run Python on ESP32-S3, just open a serial terminal and connect to the ESP32-S3 board.
+You will see the NuttShell (NSH) prompt. Run the following commands:
