-# Implementation of Extensible Variants
+# The Design and Implementation of Extensible Variants
 
 Now that we've covered how extensible records work in CGP, we can turn our attention to **extensible variants**. At first glance, it might seem like a completely different mechanism — but surprisingly, the approach used to implement extensible variants is very similar to that of extensible records. In fact, many of the same principles apply, just in the “opposite direction”.
