 *This firmware is Work in Progress and has not reached feature parity with the original yet (see below for more details)*
 
-Firmware for the control board of OpenFlexure Microscope. This is a refactor of the (original arduino code](https://gitlab.com/bath_open_instrumentation_group/sangaboard/-/blob/master/arduino_code/README.md) with some improvements to the infrastructure and features.

 ## Notable changes
 This version of the firmware uses PlatformIO rather than Arduino IDE.
 
-The code is split into the main part which mostly handles command parsing and modules which execute actual commands, allowing the firmware to be easily extensible with new features (add a module based on one of the existing ones and add a line to setup() to register it's commands and loop function).

 Motor moves now do not block command processing and a new command `stop` was added which aborts any move in progress.

 Currently works on Arduino Nano + Sangaboard v0.2. Other platforms might work with appropriate `platform.ini` and `config.h` changes and will be supported in due course.
 
 ## TODO list

 ### Original firmware feature parity
-  - [] Implement Endstops module
-  - [] Implement Light sensor modules
-  - [] Handle Sangaboardv3
-  - [] Ensure responses to commands match the original version
