Bluecheese is the redesigned Drupal.org theme. The theme must be implemented in accordance with the new Drupal.org style guide (also see the original style guide from the Mark Boulton redesign), Markup guide, and CSS guide.
This theme is only for use on official Drupal.org sites. Do not use this for businesses, local groups and other sites, which should have their own brand and identity. Questions and comments about use of this theme should go to the Drupal Association.
Access to this theme is restricted to redesign implementers team. Drupal community members who wish to work on improving the theme are able to get access to the private BZR repository so they can make patches for this issue queue.
See Contributing to Bluecheese theme for an introduction to getting involved.
Templates & function overrides
Like any theme, we override .tpl.php files and themeable functions, when needed. Site-specific code, the drupalorg module, should not be overridden, change drupalorg itself. Key modules we are using, like project usually shouldn't be overridden, unless the change really is specific to Drupal.org works. In general, try not to override, it is less code to maintain and shows off the modules we use, and Drupal core.
