 # ProgressBar
 
-<div class="callout callout-alert">
-This feature is still experimental. “Experimental” means this is an early implementation subject to drastic and breaking changes.
-</div>
-
 A simple horizontal progress bar component.
 
 Supports two modes: determinate and indeterminate. A progress bar is determinate when a specific progress value has been specified (from 0 to 100), and indeterminate when a value hasn't been specified.
 
+## Usage
+
+Render a progress bar with a certain width.
+
+The ProgressBar will expand to take all the available horizontal space of its immediate parent container element. To control its width, just wrap it in a container element (e.g `<div>`) with a specified width:
+
+```jsx
+import { ProgressBar } from '@wordpress/components';
+
+const MyProgressBar = ( props ) => {
+  return (
+		<div style={ { width: '160px' } }>
+			<ProgressBar { ...props } />
+		</div>
+	);
+};
+```
+
 ### Props
 
 The component accepts the following props:
