 2 | =======================
 3 | 
 4 | Blender importer for [OpenSCAD](http://www.openscad.org) files.
 5 | 
 6 | You need to have OpenSCAD installed on your computer for this addon to work.
 7 | 
 8 | How to install
 9 | --------------
10 | 
11 |  1. Download the addon by right clicking [this file](https://raw.githubusercontent.com/maqqr/blender-openscad-import/master/importscad.py) and choosing Save Link As...
12 |  2. In Blender, go to **File > User Preferences** and select **Install from File** and then select importscad.py
13 |  3. Set OpenSCAD executable path in the addon preferences (see image below).
14 |  
15 | On Linux-based systems, your OpenSCAD executable location is most likely `/usr/bin/openscad` if it was installed using `apt-get`.
