+## Usage
+
+Render the component passing in the required props:
+
+```jsx
+<BlockPreview
+	blocks={ blocks }
+	isScaled={ false }
+/>
+```
+
+## Props
+
+### `blocks`
+* **Type:** `array|object`
+* **Default:** `undefined`
+
+A block instance (object) or a blocks array you would like to render a preview.
