+Disqus static comment plugin for Pelican
+====================================
+
+This plugin adds a disqus_comments property to all articles.
+Comments are fetched at generation time using disqus API.
+
+Installation
+------------
+Because we use disqus API to retrieve the comments you need to create an application at
+http://disqus.com/api/applications/ which will provide you with a secret and public keys for the API.
+
+We use disqus-python package for communication with disqus API:
+``pip install disqus-python``
+
+Put ``disqus_static.py`` plugin in ``plugins`` folder in pelican installation 
+and use the following in your settings::
+
+    PLUGINS = [u"disqus_static"]
+
+    DISQUS_SITENAME = u'YOUR_SITENAME'
+    DISQUS_SECRET_KEY = u'YOUR_SECRET_KEY'
+    DISQUS_PUBLIC_KEY = u'YOUR_PUBLIC_KEY'
+
+Usage
+-----
+
+.. code-block:: html+jinja
+
+    {% if article.disqus_comments %}
+    <div id="disqus_static_comments">
+        <h4>{{ article.disqus_comment_count }} comments</h4>
+        <ul class="post-list">
+            {% for comment in article.disqus_comments recursive %}
+            <li class="post">
+                <div class="post-content">
+                    <div class="avatar hovercard">
+                        <img alt="Avatar" src="{{ comment.author.avatar.small.cache }}">
+                    </div>
+                    <div class="post-body">

+                    </div>
+                </div>
+                {% if comment.children %}
+                <ul class="children">
+                    {{ loop(comment.children) }}
+                </ul>
