 [Download the Sencha Touch SDK][sdk], and unzip the archive. Assuming that you've saved the SDK into your downloads folder (`~/Downloads/sencha-touch-2.0.0-pr3`), you can run the following commands in the terminal:
 
     cd path/to/Sencha-Touch-Boilerplate
-    cp ~/Downloads/sencha-touch-2.0.0-pr3/*.js touch/
-    cp ~/Downloads/sencha-touch-2.0.0-pr3/resources/css/* touch/resources/css/
+    cp -R ~/Downloads/sencha-touch-2.0.0-pr3/ touch/
