+THLaser Inkscape Plugin
+-----------------------
+
+This program is an Inkscape extension for exporting a set of paths as 
+gcode script. It is primarily used by members to the think|haus hacker
+space (thinkhaus.org) for use with their laser cutter. As such it is
+customized to suit our needs and so may not be your best choice if you
+are looking for a general purpose Inkscape to gcode script.
+
+This script is a fork of Gcodetools v1.2 written by Nick Drobchenko and
+is released under the same license (GPL v2).
+
+Installation
+------------
+
+Copy the files thlaser.py and thlaser.inx into your Inkscape extensions
+folder. Fire up inkscape and you will find the plugin under Extensions ->
+Export -> THLaser GCode Export.
+
+Keyboard Shortcut
+-----------------
+
+You may find it handy to assign the extension to a keyboard shortcut. 
+Include something like the following line to your inkscape keys 
+preferences file (this will bind the plugin to Ctrl+\):
+
+<bind key="backslash" modifiers="Ctrl" action="org.thinkhaus.filter.thlaser" display="true"/>
+
+You can find your keyboard preferences file:
+
+* On Linux: ~/.config/inkscape/keys/default.xml
+* Windows:  %UserProfile%\Application Data\Inkscape\keys\default.xml
+
+If that file doesn't exist, create it and include the following:
+
+<?xml version="1.0"?>
+<keys name="My Keys">
+<bind key="backslash" modifiers="Ctrl" action="org.thinkhaus.filter.thlaser" display="true"/>
+</keys>
+
