+## Quick Install
+
+Run the included `install.ps1` as Administrator from the repo root:
+
+```powershell
+# Right-click install.ps1 -> Run with PowerShell (Run as Administrator)

+## Usage (Manual)
 
 1. Run `fuckcapslock.exe` — it minimizes to the system tray immediately
 2. Caps Lock is now permanently disabled — pressing it does nothing
 3. To restore Caps Lock, right-click the tray icon and select **Exit**
