Create New Project
Click File
-> New Project...
or simply press Ctrl + N to create a new project, fill in the name and it will create a new folder with two kicad files. In this case, I will use mechanical-keyboard-tutorial
as the project name.
On this window, we will focus on Schematic Editor
and PCB Editor
, and we are going to create 9 keys (3x3) macropad / numpad.
