I have been getting to grips with Kicad. Still on W7 Ultimate 64.
There are some help files and though they are for the previous version they do let you design a basic board and generate the Gerber files. There is lots of YouTube content on Kicad going from Version 5 up to the latest Version 6.
I have been playing designing a 3 layer RGB 8x8x8 light cube from someone else's non Kicad schematics. A bit difficult for a newbie who knows nothing about electronics. Even so though I have completed the controller board, the column controller board and the Led connections board and the board that you attach the leds to. There is error checking in the eschema, the schematic drawing part and error checking in the board layout.
There is even a plugin to create Teardrop connections. There is even a 3D view. That is my Column Controller Board. Front and back views.
