+    You should implement methods(get, post, put, patch, delete) for the class to every HTTP method you want to support.
+    For example:
+        class DummyView(View):
+
+            def get(self, request, *args, **kwargs):
+                return text('I am get method')

+                return text('I am put method')
+    etc.
+    If someone try use not implemented method, there will be 405 response
+
+    If you need any url params just mention them in method definition like:
+        class DummyView(View):
+
+            def get(self, request, my_param_here, *args, **kwargs):
+                return text('I am get method with %s' % my_param_here)

+    To add the view into the routing you could use
+        1) app.add_route(DummyView(), '/')
+        2) app.route('/')(DummyView())
