 # screen-flip-rs
 Flips the screen for my hyprland config.
+
+## How it works.
+
+I have a variable in a config file for hyprland called `transform.conf` with a  single line.
+```
+$transform=0
+```
+The script will get the number and switch it to 2, or if 2 to 0.
+This file is then sourced at the top of my config and the variable can then be used for screen orientation.
