+      Arachne-pnr implements the place and route step of
+      the hardware compilation process for FPGAs. It
+      accepts as input a technology-mapped netlist in BLIF
+      format, as output by the Yosys [0] synthesis suite
+      for example. It currently targets the Lattice
+      Semiconductor iCE40 family of FPGAs [1]. Its output
+      is a textual bitstream representation for assembly by
+      the IceStorm [2] icepack command.
