linux – No configuration file on Solus i3

Well, I recently switched from Cinnamon Mint to Solus Bone
I'm used to I3wm, when I tried to install it and switch it, it starts normally, but the problem is that there are no configuration files and that keyboard shortcuts do not work.
I've Solus Bone with Mate Desktop Environment
I've removed lightdm, I start directly using the startx command
I know I could copy files, but it's a bit frustrating as this could generate other problems, any help / advice is welcome
