Rash uses the basedir library to find config files, using the list-config-files function: https://docs.racket-lang.org/basedir/index.html?q=xdg#%28def._%28%28lib._basedir%2Fmain..rkt%29._list-config-files%29%29

On Windows it searches the %APPDATA% and %LOCALAPPDATA% directories.

Unless you configure the XDG_CONFIG_HOME or XDG_CONFIG_DIRS environment variables.

FYI, I’ve pushed a documentation update to mention this in the docs.
