+#Subcategory Plugin#
+
+Adds support for subcategories in addition to article categories.
+
+Subcategories are heirachial. Each subcategory has a parent, which is either a
+regular category or another subcategory. Subcategories with the same name but 
+different parents are not the same. Their articles won't be grouped together 
+under that name.
+
+##Usage##
+
+Subcategories are an extension to categories. Add subcategories to an article's
+category metadata using a `/` like this:
+
+    Category: Regular Category/Sub-Category/Sub-Sub-category
+
+then create a `subcategory.html` template in your theme similar to the 
+`category.html` or `tag.html`
+
+In your templates `article.category` continues to act the same way. Your 
+subcategories are stored in a list `aricles.subcategories`. To create a 
+breadcrumb style navigation you might try something like this:
+
+    <nav class="breadcrumb">
+    <ol>
+        <li>
+            <a href="{{ SITEURL }}/{{ arcticle.categor.url }}">{{ article.category}}</a>
+        </li>
+    {% for subcategory in article.subcategories %}
+        <li>
+            <a href="{{ SITEURL }}/{{ category.url }}>{{ subcategory }}</a>
+        </li>
+    {% endfor %}
+    </ol>
+    </nav>
+ 
+
+##Settings##
+
+Consistent with the default settings for Tags and Categories, the default 
+settings for subcategoris are:
+    
+    'SUBCATEGORY_SAVE_AS' = os.path.join('subcategory', '{savepath}.html')
+    'SUBCATEGORY_URL' = 'subcategory/(fullurl).html'
+
+`savepath` and `fullurl` are generated recursively, using slugs. So the full
+url would be:
+    
+    category-slug/sub-category-slug/sub-sub-category-slug
+
+with `savepath` being similar but joined using `os.path.join`
