Here's how you add a new game instance:

This might be my ignorance with Linux but I'm trying to get the instances to work. So far I have been unable to do so.
I open the new instance file window but .steam is hidden so I have to grab the link from the Dolphin file explorer.
Pasting the link in the file window for ckan, it gives me an error which I think means it doesn't like the "/" vs. the other slash. I corrected this but the ksp_x64.exe still isn't showing up and the instance isn't found.

Before I post in the bug section, I thought I'd ask here just in case I'm missing something super obvious.
