 ### 6. CNC drilling and milling
 
+To drill holes and mill board outlines, `gcode` files need to be generated. Load them to `gSender` and drill and mill the board on a CNC router.

 1. To generate `gcode` files from `gerber` format, look in the [examples/CNC_mill_drill_from_gerber](./examples/CNC_mill_drill_from_gerber/Readme.md)
 2. To generate `gcode` files from `KiCad` format, look in the [examples/CNC_mill_drill_from_KiCad](./examples/CNC_mill_drill_from_KiCad/Readme.md)

 First, generate gerber files. These are the same used to order from a vendor. There are no specific settings, just:
 
 KiCad PCB Editor → File → Fabrication Outputs → Gerbers
