+## Bootstrap Icons
+
+While you won't find a built-in icon library in Bootstrap, our separate [Bootstrap Icons]({{< param icons >}}) projects is a growing set of open source SVGs you can use. While they're designed first and foremost to work with our components and documentation, you can use them in any project.

+## Additional icon sets
+
+In addition to Bootstrap Icons, we have a handful of alternative icon libraries for you to choose from. While most icon sets include multiple file formats, we prefer SVG implementations for their improved accessibility and vector support.
+
+### Preferred
+
+We've tested and used these icon sets ourselves.
+
+- [Font Awesome](https://fontawesome.com/)
+- [Feather](https://feathericons.com/)
+- [Octicons](https://octicons.github.com/)
+
+### More
+
+While we haven't tried these out, they do look promising and provide multiple formats—including SVG.
