There are a number of configuration settings for your mycomapny/settings.py file, but there are only four main ones we need to work out with to configure the Django template system: DEBUG, TEMPLATE_DEBUG, TEMPLATE_LOADERS, and TEMPLATE_DIRS.

DEBUG = True
TEMPLATE_DEBUG = True

When debugging is turned off, errors will be displayed using a friendly error template instead of showing the diagnostic information that you wouldn't want general users to see. By default, Django hides the most sensitive settings. But there are still bits of information you probably don't want the users to see.
