Thanks for keeping KiCad awesome.
As a newbie (several years with CircuitMaker), who mainly came from a MechE background I put together some documentation on how to get from Illustrator to KiCad with a minimum of fuss!
TL;DR Gerbolyzer is awesome and supports Illustrator SVGs

Hopefully this saves people some pain.
