-# **shutdown** #
+# **MAME system shutdown plugin** #
 
 Lua plugin for the MAME UI to shut down a Windows system from the menu.
+
+## Installation
+* Create a new directory called 'shutdown' in the 'plugins' subdirectory of your MAME installation.
+* Copy the files 'init.lua' and 'plugin.json' into this directory.
+* Fire up MAME.
+
+## Usage
+* Launch a machine from within MAME.
+* Pull up the config menu by (by default hit TAB on keyboard).
+* Select 'Plugin Options' and then 'System shutdown...'.
+* Choose 'Yes' to immediately shut down the Windows based system.
+
+## How it works
+Using the MAME Lua bindings to interact with the MAME UI this plugin just adds
+a menu item that executes "shutdown /s /t 0" on the underlying operating
+system (Windows). This will cause the PC to shut down gracefully without having
+to leave MAME.
+
+I wrote this plugin because my cabinet setup doesn't have a keyboard
+or mouse connected by default and I wanted a quick and dirty way to safely
+shut down with my configured controls from within MAME.
+
+## To do
+* Support other operating systems.
