I just installed bootstrap 3 theme in Drupal 7 but the subtheme folder is missing. I am new to drupal and am following tutorials. Searched online but no results. All instructions direct me to a sub theme folder in themes>bootstrap> bootstrap-subtheme. But there is no such folder. I removed the theme and reinstalled but still no folder.
