 ## Additional tools for Hack font customization
 
+### Line Spacing Adjustments
+
 **font-line** is a tool that lets you easily modify the default line spacing of Hack (20% UPM). See the [font-line repository](https://github.com/source-foundry/font-line) for more details, and be sure to check out the [line-spacing directory of the repository](https://github.com/chrissimpkins/Hack/tree/master/tools/line-spacing) for shell scripts that automate the entire process across several commonly used line spacing defaults.
