-Could someone specify what license the themes need to have to get distributed in ikiwiki or Debian? The current included theme seem to be under the GPLv2. Does the [Creative Commons Attribution 3.0 Unported License](http://creativecommons.org/licenses/by/3.0/) also work. This way a lot of free CSS templates could be included, e. g. from [freecsstemplates.org](http://www.freecsstemplates.org/).

+### Once one has enabled the 'theme' plugin in the setup file, how does one use themes?
+
+Choose one of the [[themes]] which are bundled with ikiwiki and configure ikiwiki to use it by setting this in your setup file, eg.
+
+ theme => 'blueview',
