 # Custom Attributes Block Component
 
-Gives the ability to add your own custom attributes which will be placed on the block.
+Gives the ability to add custom attributes to a block or its generated link.
 
 ## Usage
 
-The custom attribute implementation is already handled by the Block Div Block Component
+The block custom attribute implementation is already handled by the Block Div Block Component.
+For a link, render the attributes with `CustomAttributes.getCustomAttributes( attributes, 'linkCustomAttributes' )` or its block-link equivalent.
 
 ### Adding inspector controls in `edit.js`
 
 ```
 <CustomAttributes.InspectorControls />
 ```
 
+For a block with a configurable link, pass the link attribute name to add a second field below the block attributes.
+
+```
+<CustomAttributes.InspectorControls linkAttributeName="linkCustomAttributes" />
+```
+
 ### Adding attributes in `schema.js`
 
 ```
 CustomAttributes.addAttributes( attrObject )
 ```
+
+Link attributes are registered through `Link.addAttributes` or `BlockLink.addAttributes`.
