 First, you'll need OpenSCAD: http://www.openscad.org/downloads.html. I highly recommend installing the development snapshot, as they generally support more features and are relatively stable. Development snapshots are listed in their own section on the downloads page.
 
-After you have openSCAD installed, you need to download the code and run it. running `git clone https://github.com/rsheldiii/KeyV2.git` if you have git, or downloading [this zip](https://github.com/rsheldiii/KeyV2/archive/master.zip) and extracting the directory should do it. Then all you need to do is open `keys.scad` with openSCAD and you are set! It is possible to edit this project with an external editor by checking off Design => 'Automatic Reload and Preview' in OpenSCAD.

+To make your own key, all you need to do is open `keys.scad` with openSCAD and modify this line:
+
+```
+dcs_row(5) legend("⇪", size=9) key();
+``` 
+
+To be whatever you want. For example, this is for a ctrl key on an OEM keyboard:

+```u(1.25) oem_row(3) legend("ctrl", size=4.5) key();```
