 		3. On KiCAD, once you have the PCB file opened, check that there are no errors: Go to the "Inspect" Tab > "Design Rules Checker" > "Run DRC". Make sure that there are no errors. Warnings are generally fine, but  read through all of them just in case.
 		4.  Go to the "File" Tab > "Fabrication Outputs" > "Gerbers" > Specify "Output Directory" > "Generate Drill Files" (makes the holes!) > "Plot".
