 ## What is embedded-hal?
 
-In a nutshell it is a set of traits which define implementation contracts between **HAL implementations**, **drivers** and **applications (or firmwares)**. Those contracts include both capabilities (i.e. if a trait is implemented for a certain type, it is easy to see that a **HAL implementation** provides a certain capability) and methods (i.e. if you can construct a type implementing a trait it is guarenteed that you have the methods specified in the trait available).

 Some of the defined traits in **embedded-hal** are:
 * GPIO (input and output pins)
