Flask is called a "micro" framework because it doesn't directly provide features like form validation, database abstraction, authentication, and so on. Such features are instead provided by special Python packages called Flask extensions. The extensions integrate seamlessly with Flask so that they appear as if they are part of Flask itself. For example, Flask itself doesn't provide a page template engine. Templating is provided by extensions such as Jinja and Jade, as demonstrated in this tutorial.
