+**Use [ChoiceInputField](/ChoiceInputField) to display an accessible checkbox form field**. This `Checkbox` component is intended only as an ingredient for other custom components, or as a drop-in replacement for native HTML checkboxes outside of form use-cases.

+
+If you do use this component to build a custom checkbox, it should always be accompanied by a corresponding `<label>` to improve support for assistive technologies.

 ## Default example
 
 The `Checkbox` component can be used in controlled and uncontrolled modes.

+
+## Props
+
+### ChoiceInputField
+
+The container that handles the layout and passes the relevant IDs and ARIA attributes it's children.
+
+`ChoiceInputField.Label` and `ChoiceInputField.Input` are required children.
+
+<PropsTable>
+  <PropsTable.Row
+    name="children"
+    type="ChoiceInputField.Label | ChoiceInputField.Caption | ChoiceInputField.LeadingVisual | Checkbox | Radio"
+    required
+  />
+  <PropsTable.Row
+    name="disabled"
+    type="boolean"
+    defaultValue="false"
+    description="Whether the field is ready for user input"
+  />
+  <PropsTable.Row
+    name="id"
+    type="string"
+    defaultValue="a generated string"
+    description="The unique identifier for this field. Used to associate the label, validation text, and caption text"
+  />
+</PropsTable>
+
+### ChoiceInputField.Label
+
+A `ChoiceInputField.Label` must be passed, but it may be visually hidden.
+
+<PropsTable>
+  <PropsTable.Row name="children" type="React.ReactNode" description="The title that describes the choice input" />
+</PropsTable>
+
+### ChoiceInputField.Caption
+
+If this field needs additional context, a `ChoiceInputField.Caption` may be used to render hint text.
+
+<PropsTable>
+  <PropsTable.Row
+    name="children"
+    type="React.ReactNode"
+    description="The content (usually just text) that is rendered to give contextual info about the field"
+  />
+</PropsTable>
+
+### ChoiceInputField.LeadingVisual
+
+If the selectable option would be easier to understand with a visual, the `ChoiceInputField.LeadingVisual` component may be used.
+
+<PropsTable>
+  <PropsTable.Row
+    name="children"
+    type="React.ReactNode"
+    description="The visual to render before the choice input's label"
+  />
+</PropsTable>
