+Bootstrap doesn't include an icon library by default, but we have a handful of recommendations 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.
+
+- [Iconic](https://useiconic.com/open/)
+- [Octicons](https://octicons.github.com/)
+- [Entypo](http://www.entypo.com/)
+
+## More options
+While we haven't tried these out, they do look promising and provide multiple formats—including SVG.
