-REST framework also gives you to work with regular function based views...
+REST framework also allows you to work with regular function based views. It provides a set of simple decorators that wrap your function based views to ensure they receive an instance of `Request` (rather than the usual Django `HttpRequest`) and allows them to return a `Response` (instead of a Django `HttpResponse`), and allow you to configure how the request is processed.
+
+### api_view(http_method_names)
+
+The core of this functionality is the `api_view` decorator, which takes a list of HTTP methods that your view should respond to. For example, this is how you would write a very simple view that just manually returns some data:
+
+    from rest_framework.decorators import api_view
+
+    @api_view(['GET'])
+    def hello_world(request):
+        return Response({"message": "Hello, world!"})
+
+
+This view will use the default renderers, parsers, authentication classes etc specified in the [settings](settings).
+
+To override the default settings, REST framework provides a set of additional decorators which can be added to your views. These must come *after* (below) the `api_view` decorator. For example, to create a view that uses a [throttle](throttling) to ensure it can only be called once per day by a particular user, use the `throttle_classes` decorator, passing a list of throttle classes:
+
+    from rest_framework.decorators import api_view, throttle_classes
+    from rest_framework.throttling import UserRateThrottle
+
+    class OncePerDayUserThrottle(UserRateThrottle):
+            rate = '1/day'
+
+    @api_view(['GET'])
+    @throttle_classes([OncePerDayUserThrottle])
+    def view(request):
+        return Response({"message": "Hello for today! See you tomorrow!"})
+
+These decorators correspond to the attributes set on `APIView` subclasses, described above.
+
+### renderer_classes(renderer_classes)
+
+### parser_classes(parser_classes)
+
+### authentication_classes(authentication_classes)
+
+### throttle_classes(throttle_classes)
+
+### permission_classes(permission_classes)
