- Download Zen from http://drupal.org/project/zen
- Unpack the downloaded file, take the entire zen folder (which includes the README.txt file, a STARTERKIT folder, etc.) and place it in your Drupal installation under
sites/all/themes. (Additional installation folders can be used; see “Installing themes” for more information.)
- Log in as an administrator on your Drupal site and go to the Appearance page at admin/appearance (Drupal 7) or to the Themes page at admin/build/themes (Drupal 6). If you installed the theme properly, you will see the Zen theme listed.
You do not need to enable the Zen theme, but if you want to preview its markup, you can optionally make Zen the default theme.
There seems to be a conflict between some host installations of the SiteZen site builder and the Zen directory name which causes broken tabs, css files to be "not found", and other issues. To learn more about this problem and to learn its solution, visit the troubleshooting guide.
