Welcome to DrupalXpert

Drupal can be intimidating at first. Its learning curve, graphically represented with humor as an almost vertical cliff, is well known among those who have ventured to explore it. That's where DrupalXpert comes in: our purpose is to flatten that curve so that you can learn in an effective, natural and, above all, practical way.
