 Similarly, you can also apply an adjustment to line-height on a font-by-font basis by specifying a `line-height-adjustment`.

-Provide constraints for your font scales via a SASS map in the following format:

-For each scale, you'll need to specify a font-size and line-height for both the base size and the max size. Additional font-sizes and line-heights will be interpolated from these constraints.

-### Build your font scales
-
-All that's left to do is to define the sizes you need and build the scale itself:
-
-```scss
-$numb-smaller-sizes: 1;
-$numb-larger-sizes: 4;
-
-$typography: ss-build-typography($font-scales, $numb-smaller-sizes, $numb-larger-sizes);
-```
 That's it! Note that `$typography` is a key variable. This map will be used by the following mixins to lookup and apply sizes.

 ### Apply responsize sizing
 
 Use `@include ss-set-responsive-font-size($font, $size)` to apply a responsive size. The sizes available to you are based on your parameters: 
 * 0 is your base size.
 * 1, 2, 3... are your increasingly larger sizes.

 Here we just styled our h4 to have the size 1 for only the tablet breakpoint. With `ss-set-responsive-font-size()` the corresponding sizes for each other breakpoint would have also been applied.

+### Working with uppercase
+
+If you'd like to set something in all caps and have it align to your font scales, include an `uppercase-adjustment` when defining fonts:
+
+```scss
+$font-verdana: (
+	"family": unquote("Verdana, sans-serif"),
+	"font-size-adjustment": 0.89,
+	"line-height-adjustment": 0.94,
+	"uppercase-adjustment": 0.85
+);
+``
+
+Apply the uppercase style like so:
+```scss
+.h4 { 
+	@include ss-set-responsive-font-size($font-verdana, 1, $uppercase: true);
+}
+```
