Welcome to Flask's documentation. This documentation is divided in different parts. I would suggest to get started with the :ref:`installation` and then heading over to the :ref:`quickstart`. Besides the quickstart there is also a more detailed :ref:`tutorial` that shows how to create a complete (albeit small) application with Flask. If you rather want to dive into all the internal parts of Flask, check out the :ref:`api` documentation. Common patterns are described in the :ref:`patterns` section.
Flask also depends on two external libraries: the Jinja2 template engine and the Werkzeug WSGI toolkit. both of which are not documented here. If you want to dive into their documentation check out the following links:
