 ## Installation
 ```sudo defaults write com.apple.loginwindow LogoutHook /path/to/LogoutHook.command```
 
+or
+
+```/path/to/LogoutHook.command install```
+
 ## Notes
 `LogoutHook.command` highly depends on macOS `nvram` utility supporting `-x` option, which is unavailable on 10.12 and below. (Our `nvram.mojave` somehow fixes that issue by invoking it instead of system one)
