+		PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG
+		layers for mSLA 3D printers. It's compatible with any modern printer based on the RepRap toolchain, including
+		all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and
+		Machinekit controllers.
+
+		PrusaSlicer is based on Slic3r by Alessandro Ranellucci and the RepRap community.
