 Run pcb-rnd from the src/ directory (cd there, it won't find its
 files otherwise).
 
-TODO: how to run
+How to run the plugin (GUI version):
+1. run pcb-rnd (from src/)
+2. load a pcb 
+3. open the command prompt (press ':')
+4. type: SaveTo(LayoutAs, foobar.mod, kicadl)
 
+This will save the current design to foobar.mod using io_kicad_legacy.
+
+How to run the plugin (CLI version):

+echo "SaveTo(LayoutAs, foobar.mod, kicadl)" | ./pcb-rnd  --gui batch my.pcb
