+    Sometimes, users report bugs on our [issue tracker] that are caused by one
+    of our upstream dependencies, including [MkDocs], [Python Markdown],
+    [Python Markdown Extensions] or third-party plugins. A good rule of thumb is
+    to change the [`theme.name`][theme.name] to `mkdocs` or `readthedocs`, and
