 Welcome to the Klipper project!
 
-This project implements a 3d-printer firmware. There are two parts to
-this firmware - code that runs on a micro-controller and code that
-runs on a host machine. The host software does the work to build a
-schedule of events, while the micro-controller software does the work
-to execute the provided schedule at the specified times.
