PCB Design with KiCAD, part 2: PCB CAD Overview, or How PCBs are Designed

In this edition of The Hive's "PCB Design with KiCAD" series, we'll look at how PCB CAD software is structured, explain what makes KiCAD a good piece of software for learning, and provide a broad set of steps for PCB development that we'll (mostly) follow in the subsequent videos.
The PDF for this video can be found on The Hive's "PCB Fabrication" Wiki, under the "PCB Design" page:
