+        ### Leveraging Drupal (2009)
+
+        This book, published in March, 2009, when Drupal 5 was being superceded by the awesome Drupal 6, and therefore in many ways technically obsolete, was however the first "Drupal" book which offered a step-by-step agile process approach to website application development. Wiley, since the start, has offered the initial chapter (which detailed this agile based process approach) for free. It can still be obtained [on the Leveraging Drupal Wiley Website](https://www.wiley.com/en-ar/Leveraging+Drupal%3A+Getting+Your+Site+Done+Right-p-9780470410875) as a [free chapter download](https://media.wiley.com/product_data/excerpt/76/04704108/0470410876.pdf). Still valuable, in this humble author's view. Especially when the process is later [paired with Lean/UX]
