-     * Arduino Uno using [avr-hal](https://github.com/Rahix/avr-hal)
-     * ESP32-S3 using [esp-hal](https://github.com/esp-rs/esp-hal)

-## Examples
-
-There are currently two included examples:
-- [Arduino Uno](examples/arduino-uno/), based on [avr-hal](https://github.com/Rahix/avr-hal/)
-- [ESP32-S3](examples/esp32-s3/), based on [esp-hal](https://github.com/esp-rs/esp-hal).
-
-Follow the appropriate documentation for each HAL for the prerequisite set up and then simply use cargo to build and/or run each.
-
 ## TODO
 - [ ] Improve generic type interface, e.g. UnconfiguredPin improvements, better constructor, etc.
 - [ ] Improve function signatures, e.g. generic implementation for integer print functions
