Getting To Blinky 4.0

https://contextualelectronics.com/courses/getting-to-blinky/

This is where I recommend everyone start for learning KiCAD.  It's an entirely step-by-step tutorial that  gives you the foundational knowledge required for using KiCAD.

Keep in mind this Tutorial was written for KiCAD 4.0 and KiCAD 5.0 is a little different.  I would recommend installing KiCAD 4.0, following Chris's tutorials, do a couple of simple projects for fun, then upgrade to KiCAD 5.0.   Chris is working on an updated 5.0 series but if you want to start now that is what I would recommend.
