 To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type.
 
+#### Attribute Mapping
+
+To configure the JSX property to use for attribute checking, you can set global settings in your configuration file by mapping each DOM attribute to the JSX property you want to check.
+For example, you may want to allow the `for` attribute in addition to the `htmlFor` attribute for checking label associations.
+
 #### Polymorphic Components
 
 You can optionally use the `polymorphicPropName` setting to define the prop your code uses to create polymorphic components.

@@ -13,7 +13,7 @@ Enforce label tags have associated control.
 There are two supported ways to associate a label with a control:
 
 - nesting: by wrapping a control in a label tag
-- id: by using the prop `htmlFor` as in `htmlFor=[ID of control]`
+- id: by using the prop `htmlFor` (or any configured attribute) as in `htmlFor=[ID of control]`
 
 To fully cover 100% of assistive devices, you're encouraged to validate for both nesting and id.
