+### Theme Variations
+
+Many themes are more *theme families* then only one theme.
+*duepunto zero* and *vier* allow easily to add new theme variation.
+We will go through the process of creating a new variation for *duepunto zero*.
+The same (well almost, some names change) procedure applies to the *vier* theme.
+And similar steps are needed for *quattro* but this theme is using [lessc](http://lesscss.org/#docs) to maintaine the CSS files..
