+## Features
+
+* Generate Julia Sets, Tricorn, Burning Ship or Mandelbrot Fractals
+* Set complex plane, bailout, and zoom coordinates / level
+* Output calculated data as images (PNM / JPEG / PNG) or export as csv
+* Different coloring algorithms
+* Fast platform independent code written in C++11 using the cmake build system
