This is for OS: arch, DE: KDE, WM: KWin (Wayland).
At the time of the last commit, the kernel is: Linux 6.10.10-arch1-1.
It should be fine to simply copy everything to ~/.config, except for the .rc files in the top level directory here; they should be in ~/. (except if one has a custom ZSH_CONFIG path ..etc).
Other rc config files are in ./dots/rcs/ and should be copied to ~/.config/.
For a more general case, don't copy anything from the dots/rcs/ directory.
