Corrections related to the new updates and changes in the way drupal-boilerplate works have been applied:

• MAKEFILE - Consistence between all setup commands
• Rename Behat default features as examples
• Expand documentation in case you do not want minimal Drupal
• Replace unnecessary drush alias
• Remove ci split no longer used

LGTM. I've changed the explanation of drush site install to be more precise. Merging, thanks!
