+This tutorial will walk you through creating a basic blog application
+called Flaskr. Users will be able to register, log in, create posts,
+and edit or delete their own posts. You will be able to package and
+install the application on other computers.

+It's assumed that you're already familiar with Python. The `official
+tutorial`_ in the Python docs is a great way to learn or review first.

+
+While it's designed to give a good starting point, the tutorial doesn't
+cover all of Flask's features. Check out the :doc:`/quickstart` for an
+overview of what Flask can do, then dive into the docs to find out more.
+The tutorial only uses what's provided by Flask and Python. In another
+project, you might decide to use :doc:`/extensions` or other libraries
+to make some tasks simpler.

+
+Flask is flexible. It doesn't require you to use any particular project
+or code layout. However, when first starting, it's helpful to use a more
+structured approach. This means that the tutorial will require a bit of
+boilerplate up front, but it's done to avoid many common pitfalls that
+new developers encounter, and it creates a project that's easy to expand
+on. Once you become more comfortable with Flask, you can step out of
+this structure and take full advantage of Flask's flexibility.

+:gh:`The tutorial project is available as an example in the Flask
+repository <examples/tutorial>`, if you want to compare your project
+with the final product as you follow the tutorial.
