+# Save Component
+
+This React [component](https://github.com/WordPress/gutenberg/blob/57da3c91a166d917a2a9de98177be9c3dfe07ee5/docs/reference-guides/block-api/block-edit-save.md#save) determines what's saved to the database.
+
+Its only job is to return markup.
+
+The returned markup is saved to the database as HTML, with attributes stored in a comment:
+
+```html
+<!-- wp:progress-indicator/progress-indicator {"color":"#ffe2c7","currentStep":3,"numberOfSteps":7} -->
+<div class="wp-block-progress-indicator-progress-indicator">
+```
+
+And that saved markup is what displays on the front-end.
+
+Unlike the `Edit` component, this component isn't interactive.
+
+So you won't see `useState()` or REST API calls in `Save`.
+
+The wrapping element of `Save` [should have](https://github.com/WordPress/gutenberg/blob/57da3c91a166d917a2a9de98177be9c3dfe07ee5/docs/reference-guides/block-api/block-edit-save.md#block-wrapper-props-1) `useBlockProps.save()` spread into it:
+```jsx
+export default function Save( { attributes } ) {
+	const blockProps = useBlockProps.save();
+
+	return <div { ...blockProps }>
+```
+
+This adds classes, and sometimes attributes from the [Block Supports](https://github.com/WordPress/gutenberg/blob/57da3c91a166d917a2a9de98177be9c3dfe07ee5/docs/reference-guides/block-api/block-supports.md#supports) API:
+```html
+<div class="wp-block-progress-indicator-progress-indicator">
+```
+
+## Exercise
+You'll see a lot of [block validation](https://github.com/WordPress/gutenberg/blob/57da3c91a166d917a2a9de98177be9c3dfe07ee5/docs/reference-guides/block-api/block-edit-save.md#validation) notices like:
+
+>This block contains unexpected or invalid content.
+
+This is normal when editing the `Save` component.
+
+Click 'Attempt Block Recovery' and continue developing:
+
+![unexpected-invalid-content](https://user-images.githubusercontent.com/4063887/152257716-0477a0dc-d666-4249-a5e4-65c96a1e7817.gif)
+
+Once you finish this `Save` component, this block will be done.
+
+It'll display on the front-end.
