+Flask
+=====
+
+Flask is a lightweight `WSGI`_ web application framework. It is designed
+to make getting started quick and easy, with the ability to scale up to
+complex applications. It began as a simple wrapper around `Werkzeug`_
+and `Jinja`_ and has become one of the most popular Python web
+application frameworks.
+
+Flask offers suggestions, but doesn't enforce any dependencies or
+project layout. It is up to the developer to choose the tools and
+libraries they want to use. There are many extensions provided by the
+community that make adding new functionality easy.
+
+
+Installing
+----------
+
+Install and update using `pip`_:
+
+.. code-block:: text
+
+    pip install -U Flask
+
+
+A Simple Example
+----------------
+
+.. code-block:: python
+
+    from flask import Flask
+
+    app = Flask(__name__)
+
+    @app.route("/")
+    def hello():
+        return "Hello, World!"
+
+.. code-block:: text
+
+    $ env FLASK_APP=hello.py flask run
+     * Serving Flask app "hello"
+     * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
