Creating a django master template

Hello my question is this, I am following this tutorial link and leave the point where you go to the templates directory and create an html file but do not know or there is not a directory of that type, check the settings.py and do not know if that's where adds a directory (I guess that by previous versions of django I did not do it like in the tutorial or skipped that part)

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

is where I should indicate a directory to read the templates and if that were the case: Is that directory created in an app or in the project folder?
