+The `Checkbox` component now accepts `string[]` as the `value` prop. This is to conform with the native input prop type. If a string array is passed, it will be stringified, just like in the native input element. ([#2456](https://github.com/ariakit/ariakit/pull/2456))

   Rendering a custom <a href="/components/checkbox">Checkbox</a> as a <code>button</code> element in React, while keeping it accessible to screen reader and keyboard users.
 </p>
 
+<aside data-type="note" title="Need to render a native checkbox element?">
+
+This example demonstrates the rendering of a button element. However, if you intend to render the `Checkbox` as a form control or require the preservation of native input element properties for any specific purpose, please refer to the [Custom Checkbox](/examples/checkbox-custom) example.

+
+## Activating on <kbd>Enter</kbd>
+
+By default, native checkbox elements are activated on <kbd>Space</kbd>, but not on <kbd>Enter</kbd>. The Ariakit `Checkbox` component allows you to control this behavior using the [`clickOnEnter`](/apis/checkbox#clickonenter) and [`clickOnSpace`](/apis/checkbox#clickonspace) props. However, when rendering the `Checkbox` as any non-native input element, the `clickOnEnter` prop will be automatically set to `true`.
+
+## Reading the state
+
+In this example, we're reading the [`value`](/apis/checkbox-store#value) state from the checkbox store to render the button's text. This is done by using the selector form of the [`useState`](/apis/checkbox-store#usestate) hook:
+
+```jsx
+const label = checkbox.useState((state) =>
+  state.value ? "Checked" : "Unchecked"
+);
+```
+
+Learn more about reading the state on the [Component stores](/guide/component-stores#reading-the-state) guide.
+
 ## Styling
 
 When rendering the `Checkbox` component as a non-native `input` element, the `:checked` pseudo-class is not supported. To style the checked state, use the `aria-checked` attribute selector:
 
 ```css
 .button[aria-checked="true"] {
   background-color: hsl(204 100% 40%);
-  color: hsl(204, 20%, 100%);
+  color: hsl(204 20% 100%);
 }
 ```
