-#### Passthrough extension
+To avoid a conflict when enabling the Hugo Goldmark Extras subscript extension, if you want to render subscript and strikethrough text concurrently you must:
+
+1. Disable the Goldmark strikethrough extension
+2. Enable the Hugo Goldmark Extras delete extension
+
+For example:
+
+{{< code-toggle file=hugo >}}
+[markup.goldmark.extensions]
+strikethrough = false
+
+[markup.goldmark.extensions.extras.delete]
+enable = true
+
+[markup.goldmark.extensions.extras.subscript]
+enable = true
