title: How to add missing read-more link to drupal 7 teaser
body: <p>When customizing a drupal 7 theme about a year ago I removed the code that displays the read-more link at the end of teasers. </p>
  
  <p>I need to add this code back to show the read-more links now, but I have totally forgotten where to put this code in.</p>
  
  <p>Any help?</p>
  
  <p>Thanks</p>
