Welcome to Flask's documentation. Get started with :doc:`installation`
and then get an overview with the :doc:`quickstart`. There is also a
more detailed :doc:`tutorial/index` that shows how to create a small but
complete application with Flask. Common patterns are described in the
:doc:`patterns/index` section. The rest of the docs describe each
component of Flask in detail, with a full reference in the :doc:`api`
section.

Flask depends on the `Jinja`_ template engine and the `Werkzeug`_ WSGI
toolkit. The documentation for these libraries can be found at:

- `Jinja documentation <https://jinja.palletsprojects.com/>`_
- `Werkzeug documentation <https://werkzeug.palletsprojects.com/>`_

User's Guide
------------

Flask provides configuration and conventions, with sensible defaults, to get started.
This section of the documentation explains the different parts of the Flask framework
and how they can be used, customized, and extended. Beyond Flask itself, look for
community-maintained extensions to add even more functionality.
