In browsers where the [Page Visibility API](https://www.w3.org/TR/page-visibility/) is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).
+The carousel supports swipe gestures (left and right) using [HammerJS]({{ site.cdn.hammer }}). For this to function correctly you need to include HammerJS before Bootstrap or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains HammerJS.
+
Please be aware that nested carousels are not supported, and carousels are generally not compliant with accessibility standards.
Lastly, if you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
