 # `numlock-indicator`
 
-**\* Important: You'll need to manually use taskbar settings to pin the taskbar icon so it's always visible!**
-
 This powershell script adds a small indicator to the system tray to indicate when the numlock is enabled.
 
+## Install
+
+1. Run `install.ps1` in an **administrator** powershell terminal. This script will add a task scheduler task to start up the indicator on login. Admin privileges are required to add task scheduler tasks.

 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???)
