+Deploying Responder
+===================
+
+You can deploy Responder anywhere you can deploy a basic Python application.
+
+Docker Deployment
+-----------------
+
+Assuming existing ``api.py`` and ``Pipfile.lock`` containing ``responder``.
+
+``Dockerfile``::
+
+    from kennethreitz/pipenv
+
+    COPY . /app
+    CMD python3 api.py
+
+That's it!
+
+Heroku Deployment
+-----------------
+
+The basics::
+
+    $ mkdir my-api
+    $ cd my-api
+    $ git init
+    $ heroku create
+    ...
+
+Install Responder::
+
+    $ pipenv install responder
+    ...
+
+Write out an ``api.py``::
+
+    import responder
+
+    api = responder.API()
+
+    @api.route("/")
+    async def hello(req, resp):
+        resp.text = "hello, world!"
+
+    if __name__ == "__main__":
+        api.run()
+
+Write out a ``Procfile``::
+
+    web: python api.py
+
+That's it! Next, we commit and push to Heroku::
+
+    $ git add -A
+    $ git commit -m 'initial commit'
+    $ git push heroku master

+- ASGI framework, the future of Python web services.
+- The ability to mount any ASGI / WSGI app at a subroute.
+- *f-string syntax* route declaration.
+- Mutable response object, passed into each view. No need to return anything.

+
+Mount a WSGI App (e.g. Flask)
+-----------------------------
+
+Responder gives you the ability to mount another ASGI / WSGI app at a subroute::
+
+    import responder
+    from flask import Flask
+
+    api = responder.API()
+    flask = Flask(__name__)
+
+    @flask.route('/')
+    def hello():
+        return 'hello'
+
+    api.mount('/flask', flask)
+
+That's it!
+
+Single-Page Web Apps
+--------------------
+
+If you have a single-page webapp, you can tell Responder to serve up your ``static/index.html`` at a route, like so::
+
+    api.add_route("/", static=True)
+
+This will make ``index.html`` the default response to all undefined routes.
+
+Reading / Writing Cookies
+-------------------------
+
+Responder makes it very easy to interact with cookies from a Request, or add some to a Response::
+
+    >>> resp.cookies["hello"] = "world"
+
+    >>> req.cookies
+    {"hello": "world"}
+
+
+Using Cookie-Based Sessions
+---------------------------
+
+Responder has built-in support for cookie-based sessions. To enable cookie-based sessions, simply add something to the ``resp.session`` dictionary::
+
+    >>> resp.session['username'] = 'kennethreitz'
+
+A cookie called ``Responder-Session`` will be set, which contains all the data in ``resp.session``. It is signed, for verification purposes.
+
+You can easily read a Request's session data, that can be trusted to have originated from the API::
+
+    >>> req.session
+    {'username': 'kennethreitz'}
+
+**Note**: if you are using this in production, you should pass the ``secret_key`` argument to ``API(...)``.
