Tag your references in Drupal:
- Log in to your Drupal admin panel.
- Click on “Site building,” and then “Blocks”.
- Click on “Add block.”
- Copy and paste the Reftagger script in a new block. Give it a name you’ll remember,
such as “Reftagger.”
- Change the input format to full HTML.
- Save the block.
- Activate your block as a footer block, and every reference on your site will be tagged.
