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 Werkzeug WSGI toolkit, the Jinja template engine, and the Click CLI toolkit. Be sure to check their documentation as well as Flask's when looking for information.

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.
