 """
 Django settings for InvenTree project.
 
-Generated by 'django-admin startproject' using Django 1.10.6.
+In practice the settings in this file should not be adjusted,
+instead settings can be configured in the config.yaml file
+located in the top level project directory.
 
-For more information on this file, see
-https://docs.djangoproject.com/en/1.10/topics/settings/
+This allows implementation configuration to be hidden from source control,
+as well as separate configuration parameters from the more complex
+database setup in this file.
 
-For the full list of settings and their values, see
-https://docs.djangoproject.com/en/1.10/ref/settings/
