+# `numlock-indicator`
+
+This powershell script adds a small indicator to the system tray to indicate when the numlock is enabled.
+
+Copy files to some directory and run `powershell systray.ps1`. You can also run `start.sh` to ensure that one copy of the script is always active.
+
+I wrote this because for some reason, my laptop keyboard has no LED indicator for the numlock key (yet they have one for capslock and speakers???)
+
+Feel free to replace `icon.png` with any bitmap icon if you don't like my terrible pixel art.
