place the darkvoid.json file to your zed themes folder, generally $XDG_CONFIG/zed/themes.
then you can issue the cmd-k cmd-t keyshort to open the theme switcher and select "Dark Void" or set
# $XDG_CONFIG/zed/settings.json
{
theme = "Dark Void"
}to your zed settings.json file.
be darky and happy (:
