+## FileUploadParser
+
+Parses raw file upload content. Returns a `DataAndFiles` object. Since we expect the whole request body to be a file content `request.DATA` will be None, and `request.FILES` will contain the only one key `'file'` matching the uploaded file.
+
+The `filename` property of uploaded file would be set to the result of `.get_filename()` method. By default it tries first to take it's value from the `filename` URL kwarg, and then from `Content-Disposition` HTTP header. You can implement other behaviour be overriding this method.
+
+Note that since this parser's `media_type` matches every HTTP request it imposes restrictions on usage in combination with other parsers for the same API view.
+
+Basic usage expamle:
+
+    class FileUploadView(views.APIView):
+        parser_classes = (FileUploadParser,)
+
+        def put(self, request, filename, format=None):
+            file_obj = request.FILES['file']
+            # ...
+            # do some staff with uploaded file
+            # ...
+            return Response(status=204)

-## Uploading file content
-
-If your custom parser needs to support file uploads, you may return a `DataAndFiles` object from the `.parse()` method.  `DataAndFiles` should be instantiated with two arguments.  The first argument will be used to populate the `request.DATA` property, and the second argument will be used to populate the `request.FILES` property.
