### What license do themes need to have for distribution?
-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',

+
+### How to enable properly?
+
+So I added "theme" to my config file's "add_plugins" directive, and uncommented the "theme: actiontabs" line. I then ran "ikwiki --setup wiki.setup" and... no change on reload.
+
+I'm on Ubuntu 16.04. Any idea what I'm doing wrong? --[[STrRedWolf]]
