+### Config files
+SwaySwitch uses two configuration files, one is supplied with the package and is installed to /etc/sway/config.d/swayswitch.conf. It contains default keybindings for Sway.
+The other on is optionally supplied by the user as $HOME/.local/swayswitch/config in toml format.
+
+Possible options are:
+```
+label_len = 20
+icon_size = 128
+```
+The example above is the default options. ```label_len``` is the total length of the text label above buttons and ```icon_size``` is the size of the icons in pixels.
