 ### Keyboard interaction
 
-The Carbon number input replicates the behavior of the stock HTML component. The number input takes a single tab stop. The + and - buttons, operable by pointer, are not in the tab order. When the input has focus, the arrow keys give keyboard users the same ability to incrementally adjust the values. As well, users can directly type numeric values in the input. Only numerals are allowed to be entered.

 ### Error handling
-Carbon provides errors and warning messages to assistive technology. This is an improvement on the stock HTML number input, which simply prevents the typing of alphabetic characters without explanation. Carbon also adds an error or warning icon and puts error messages in red as a further visual cue.

 ### Cue users for value and step
-Carbon offers the ability for the author to set minimum and maximum values for the input. When setting limits on number entry, designers should warn the user in advance, instead of users discovering limits through an error message. This is particularly the case if designers alter the step value, which determines the increment change when activating the +/- buttons or arrow keys. If a user directly enters a value that does not match the step increment, it will be disallowed for no apparent reason, so advanced warnings are crucial.

 ## Usage
 
-You can use `@carbon/themes` in JavaScript or Sass by including this package in
-your project. By default, `@carbon/themes` provides a set of color tokens that
-are pre-defined for a specific theme. Currently, we offer the following color
-themes: white, gray 10, gray 90, gray 100 .
+There are three ways to utilize Carbon Themes. First, and maybe the simplest way
+is to bring in our

+component and pass your desired theme as a prop. Second, if you need more
+granular control of where themes are applied or access to specific theming
+tokens when and you're using `@carbon/styles` or `@carbon/react` you already
+have access to sass theming with no need for an extra package. Lastly, you can
