 ## Running slock
 
 Simply invoke the 'slock' command. To get out of it, enter your password.
+
+## Blur effect
+
+This fork leverages picom's new kawase blur method instead of taking a screenshot, blur it using ImageMagick without hardware acceleration and then set it as the lock screen wallpaper.
+The end result is much higher performance and much lower latency.
+
+Currently, you will need to enable the experimental backend in picom using `picom --experimental-backends`, you can check out my picom config [here](https://github.com/khuedoan/dotfiles/blob/master/.config/picom/picom.conf#L29).
