+Multi parts posts
+-----------------
+
+The multi-part posts plugin allow you to write multi-part posts.
+
+In order to mark posts as part of a multi-part post, use the `:parts:` metadata:
+
+    :parts:  MY_AWESOME_MULTI_PART_POST
+
+You can then use the `article.metadata.parts_articles` variable in your templates 
+to display other parts of current post.
+
+For example:
+
+    {% if article.metadata.parts_articles %}
+        <ol class="parts">
+        <li>Post parts</li>
+        {% for part_article in article.metadata.parts_articles %}
+            {% if part_article == article %}
+                <li class="active">
+                    <a href='{{ SITEURL }}/{{ part_article.url }}'>{{ part_article.title }}
+                    </a>
+                </li>
+            {% else %}
+                <li>
+                    <a href='{{ SITEURL }}/{{ part_article.url }}'>{{ part_article.title }}
+                    </a>
+                </li>
+            {% endif %}
+        {% endfor %}
+        </ol>
+    {% endif %}
