I'm not intended to push until I get that new Composerizing verb to be into the dictionary, but I wan't to leave track of my experience about how to implement Composer on our old Drupal projects where it wasn't used before, and why move to this new work schema so maybe some developers who were habituated to work with older versions of Drupal, and I'm talking about Drupal 7 and early versions of 8, can find here a useful reference to guide them through their way to truth and happiness.
