 Motor moves now do not block command processing and a new command `stop` was added which aborts any move in progress.
 
 ## Hardware
-This is mainly intended for Sangaboard control boards and all configuration for these is already in `boards.h`, but it can also be used on different platforms (pi pico, stm32 (bluepill)). To use a custom board based on any of these platforms adjust `boards.h` to match your wiring.

 If you have additional hardware connected to the board (Endstops, Light sensor) support for these can be enabled in `config.h`.
