Hello,

I tried to create the config as documented but I am strugling.
a) it wants the config file on some location as per manual, okay. Is the
format key=value in each line or is that just a single line as shown in
the manpage?

Also, what exactly "any directory to contain Proton's runtime files."?
Is that a new directory which I am supposed to create for new files? Or
is that some folder from the Steam installation, but then how to
identify it?

Also, could the tool not be slightly extended to guess the default
values (in $HOME/.steam) and use them if no config was found?

Best regards,
Eduard.
