 ## Embedded-HAL
 
-Embedded-HAL is a standard set of traits meant to permit communication between MCU implementations and hardware drivers
-like this one.  Any microcontroller that implements the
-[`spi::FullDuplex<u8>`](https://docs.rs/embedded-hal/0.2.3/embedded_hal/spi/trait.FullDuplex.html) interface can use
-this driver.
