KiCad and ESP32 guide reading

Today I went through the whole Blare guide and learnt about the working of xiao ESP32 and how kicad works.
Funny thing is that i did use onshape for one project before and i was stumped about how do i get my PCB onto onshape but instead of looking for a way to import it like a wise person.
I REMADE the whole PCB in part studio in OnShape. Obviously it was very wrong schematics and dimension wise so reading this guide did help.
In the next one im gonna start (and hopefully end) with schematics and PCB atleast.
