-A tool for switching user's software configs
+Apply visual themes to various apps with ease.
+
+## Kitty
+Themer symlinks ~/.config/kitty/current-theme.conf to the
+file found within theme directory.
+So:
+1. touch ~/.config/kitty/current-theme.conf
+2. echo 'include current-theme.conf' >> ~/.config/kitty/kitty.conf
+If you even called kitten theme 'Some Theme' then
+your setup is fine and ready for Themer.
+
+## Niri
+If ~/.config/niri/configs/ dir exists then
+config is assembled from this dir + theme.
+Else niri.kdl from theme directory is considered the whole config and
+Themer symlinks ~/.config/niri/config.kdl to you niri.kdl inside
+theme directory.
+
+## Sway
+Replaces either ~/.config/sway/theme.conf or whole config.
+
+## Swaybg
+If using swaybg in other compositor besides sway
+then it must be a systemd unit for Themer to manage it.
+
+Put the following to ~/.config/systemd/user/swaybg.service
+```
+[Unit]
+PartOf=graphical-session.target
+After=graphical-session.target
+Requisite=graphical-session.target
+
+[Service]
+ExecStart=/usr/bin/swaybg -m fill -i "%h/.config/swaybg/wallpaper"
+Restart=on-failure
+```
+
+1. mkdir ~/.config/swaybg
+2. ln -s /path/to/any/wallpaper  ~/.config/swaybg/wallpaper
+3. systemctl --user daemon-reload
+4. systemctl --user add-wants niri.service swaybg.service
