+Hugo will automatically parse the markdown for your content and create
+a Table of Contents you can use to guide readers to the sections within
+your content. 
+
+## Usage
+
+Simply create content like you normally would with the appropriate
+headers. 
+
+Hugo will take this markdown and create a table of contents stored in the
+[content variable](/layout/variables) .TableOfContents
+
+
+## Template Example
+
+This is example code of a [single.html template](/layout/content).
+
+    {{ template "chrome/header.html" . }}
+        <div id="toc" class="well col-md-4 col-sm-6">
+        {{ .TableOfContents }}
+        </div>
+        <h1>{{ .Title }}</h1>
+        {{ .Content }}
+    {{ template "chrome/footer.html" . }}
