+CharaChorder Engine is a multichip module that enables you to build your own 
+CCOS powered text entry device. If you are interested in learning how to utilize
+CharaChorder Engine, please visit the `CharaChorder Engine Discord channel <https://discord.gg/VngNWSyZJb>`_

+Design
+******
+
+The Engine is designed primarily to work with a MCU to receive inputs (through 
+UART and later I2C or SPI), process the chording logic, query the onboard chordmap
+library, and output the results back to the MCU (again over UART and later I2C or
+SPI). However, the layout of the Engine exposes USB pins, which could have a future
+capability for direct USB HID output. This could be limiting for some developers,
+as they may want to control their HID reports themselves through their MCU.
+
+Communicating with Engine Devices
+*********************************
+
+Like other CCOS powered devices, any device with CharaChorder Engine can use the 
+full power of the :doc:`Serial API<SerialAPI>`.
