-# deca-mandelbrot
-The Terasic DECA board as a mandelbrot accelerator.
+# FPGA Mandelbrot
+FPGA boards as mandelbrot accelerators.
 This is a hobby project to explore parallel computation/pipelining
 on a FPGA.
 
-## current status
-* working: nine 72 bit fixed point mandelbrot cores run at 60 MHz
-* still needs improvement: better resource usage, pipelining, more efficient USB data transfer
-* basic interactive Gtk app works
+## Supported Boards
+* The Terasic DECA board over high speed USB2
