 ### Recommendations
 
 * Use buttons to move though a transaction.
 * Aim to use only one button per page.
 * Avoid excessively long button text.
 * Make sure the button text describes an action.
+* Avoid disabling buttons. Use error messaging to provide feedback rather than a disabled button.
 
 By default, Buttons will be displayed in the `primary` variant. Use primary buttons for the main action on a page or 
 in a form.
