+# Generic Architecture Example
+
+This contains a simple, artificial, example of the nextpnr generic API.
+
+ - simple.py procedurally generates a simple FPGA architecture with IO at the edges,
+ logic slices in all other tiles, and interconnect only between adjacent tiles
+
+ - report.py stores design information after place-and-route to blinky.txt in place
+ of real bitstream generation
+
+ - Run blinky.sh to build an example design on the FPGA above \ No newline at end of file
