+# LinkControl
+
+The `LinkControl` component allows for adding a link. It is intended for use within the block settings UI that appears in the sidebar.
+
+The link control is just a wrapper for the core URL input component. The only difference is the visual appearance and API is more aligned with other sidebar controls such as the TextControl.
+
+## Usage
+
+```js
+const { InspectorControls } = wp.blocks;
+const { LinkControl } = hm.controls;
+const { attributes, setAttributes } = props;
+
+<InspectorControls>
+    <LinkControl
+        label="Link"
+        help="Some description text"
+        value={ attributes.link }
+        onChange={ link => setAttributes( { link } ) }
+    />
+</InspectorControls>
+```
