+# Prusa Firmware MK3
+
+This repository contains the source code and the development versions of the firmware running on the [Original Prusa i3](https://prusa3d.com/) MK3S/MK3/MK2.5S/MK2.5 line of printers.
+
+The latest official builds can be downloaded from [Prusa Drivers](https://www.prusa3d.com/drivers/). Pre-built development releases are also [available here](https://github.com/prusa3d/Prusa-Firmware/releases).
+
+The firmware for the Original Prusa i3 printers is proudly based on [Marlin 1.0.x](https://github.com/MarlinFirmware/Marlin/) by Scott Lahteine (@thinkyhead) et al. and is distributed under the terms of the [GNU GPL 3 license](LICENSE).
