+  To style butterfly in sass, you need to have the libsass python library installed.
+
+  You will have to:
+    $ cp {main} ~/.butterfly/style.sass
+  or for system wide:
+    # cp {main} /etc/butterfly/style.sass
+  and then edit this file.
+
+  You can also copy the imported sass files in the same dir.
+  Sass files are compiled on the fly so just reload your tab to see the changes.
+
+  It is also possible to use a style.css file and re do all the styling in css exclusively.\
