-Tag cloud
-=========
-
-If you want to generate a tag cloud with all your tags, you can do so using the
-following settings.
-
-================================================    =====================================================
-Setting name (followed by default value)            What does it do?
-================================================    =====================================================
-``TAG_CLOUD_STEPS = 4``                             Count of different font sizes in the tag
-                                                    cloud.
-``TAG_CLOUD_MAX_ITEMS = 100``                       Maximum number of tags in the cloud.
-================================================    =====================================================
-
-The default theme does not include a tag cloud, but it is pretty easy to add one::
-
-    <ul class="tagcloud">
-        {% for tag in tag_cloud %}
-            <li class="tag-{{ tag.1 }}"><a href="{{ SITEURL }}/{{ tag.0.url }}">{{ tag.0 }}</a></li>
-        {% endfor %}
-    </ul>
-
-You should then also define CSS styles with appropriate classes (tag-1 to tag-N,
-where N matches ``TAG_CLOUD_STEPS``), tag-1 being the most frequent, and
-define a ``ul.tagcloud`` class with appropriate list-style to create the cloud.
-For example::
-
-    ul.tagcloud {
-      list-style: none;
-        padding: 0;
-    }
-
-    ul.tagcloud li {
-        display: inline-block;
-    }
-
-    li.tag-1 {
-        font-size: 150%;
-    }
-
-    li.tag-2 {
-        font-size: 120%;
-    }
-
-    ...
