-#### Use `VoteMixin` for REST API
+### Use tags template
+
+There are two template tags you can use in template: 
+1. `vote_count` to get vote count for a model instance
+2. `vote_exists` to check whether current user vote for the instance
+
+``` html
+{% load vote %}
+<ol>
+    {% for comment in comments %}
+    <li>
+        {{comment.content}} - up:{% vote_count comment "up" %} - down: {% vote_count comment "down" %} - exists_up:
+        {% vote_exists comment user "up" %} - exists_down: {% vote_exists comment user "down"%}
+    </li>
+    {% endfor %}
+</ol>
+```
+
+### Use `VoteMixin` for REST API
+
+Install [django-rest-framework](https://github.com/encode/django-rest-framework/)
 
 ``` python
+from rest_framework.viewsets import ModelViewSet
+from vote.views import VoteMixin
+
 class CommentViewSet(ModelViewSet, VoteMixin):
     queryset = Comment.objects.all()
     serializer_class = CommentSerializer
