+## Fragment shortcode
+
+The `fragment` shortcode makes content appear incrementally.
+
+```
+{{%/* fragment */%}} One {{%/* /fragment */%}}
+{{%/* fragment */%}} Two {{%/* /fragment */%}}
+{{%/* fragment */%}} Three {{%/* /fragment */%}}
+```
+
+{{% fragment %}} One {{% /fragment %}}
+{{% fragment %}} Two {{% /fragment %}}
+{{% fragment %}} Three {{% /fragment %}}
+

+
+## Frag shortcode
+
+The `frag` shortcode more terse than `fragment`. It accepts a `c` attribute.
+
+```
+{{</* frag c="One" */>}}
+{{</* frag c="Two" */>}}
+{{</* frag c="Three" */>}}
+```
+
+{{< frag c="One" >}}
+{{< frag c="Two" >}}
+{{< frag c="Three" >}}
+
+---
+
+Both `fragment` and `frag` accept two additional parameters:
+
+- `class`: sets the class of the wrapping `span` element
+- `index`: controls the order in which sections will appear
