+## Disabling `noscript` support
+
+By default, Jekyll Gist will make an HTTP call per Gist to retrieve the raw content of the Gist. This information is used to propagate `noscript` tags for search engines and browsers without Javascript support. If you'd like to disable this feature, for example, to speed up builds locally, simply add the following to your site's `_config.yml`:
+
+```yml
+gist:
+  noscript: false
+```
