 Supported Ports
 ==============================
 
-Adafruit's CircuitPython currently has limited support with a focus on supporting the Atmel SAMD
-and ESP8266.
+CircuitPython supports a number of microcontroller families. Support quality for each varies
+depending on the active contributors for each port.
+
+Adafruit sponsored developers are actively contributing to atmel-samd, mimxrt10xx, nrf and stm
+ports. They also maintain the other ports in order to ensure the boards build. Additional testing
+is limited.

-=========
+SAMD21 and SAMD51
+==================
 
-This port brings MicroPython to SAMD21x18 based development boards under the name
-CircuitPython. Supported boards include:
-
--  Adafruit CircuitPlayground Express
--  Adafruit Feather M0 Basic
--  Adafruit Feather M0 Express
--  Adafruit Metro M0 Express
--  Adafruit M0 Bluefruit LE
--  Arduino Zero
--  Arduino MKR Zero
--  Arduino Nano 33 IoT
+This port supports many development boards that utilize SAMD21 and SAMD51 chips. See
+https://circuitpython.org/downloads for all supported boards.

+LiteX (FPGA)
+============
+
+`LiteX <https://github.com/enjoy-digital/litex>`_ is a Python-based System on a Chip (SoC) designer
+for open source supported Field Programmable Gate Array (FPGA) chips. This means that the CPU
+core(s) and peripherals are not defined by the physical chip. Instead, they are loaded as separate
+"gateware". Once this gateware is loaded, CircuitPython can be loaded on top of it to work as
+expected.
+
+Installation
+-------------
+
+You'll need ``dfu-util`` to install CircuitPython on the Fomu.
 
 Make sure the foboot bootloader is updated. Instructions are here: https://github.com/im-tomu/fomu-workshop/blob/master/docs/bootloader.rst
 
-Once you've updated the bootloader, you should know how to use `dfu-util`. It's pretty easy!
