+# Summary component
+
+```{versionadded} volto-light-theme 6.0.0-alpha.13
+
+```
+
+The `Summary` component is used to render key information about a content item in several locations:
+
+- listing block
+- search block
+- teaser block
+
+```{figure} /_static/summary.png
+:alt: Screenshot of a Volto listing highlighting the Summary component
+:target: /_static/summary.png
+The default summary includes the kicker, title, and description.
+```
+
+## Built-in summary implementations
+
+Volto Light Theme includes the following summary implementations for core content types:
+
+- `DefaultSummary`: Includes the kicker, title, and description. This component is used for any content type that doesn't have a specific summary component registered.
+- `NewsItemSummary`: Includes the publication date, kicker, title, and description for News Items.
+- `EventSummary`: Includes the start and end date, kicker, title, and description for Events.
+- `FileSummary`: Includes the file size and type for Files.
+
+## Register a summary for a content type
+
+You can create a custom summary implementation and register it for a content type.
+
+The summary component must accept `item` and `HeadingTag` as props.
+Here is an example which renders the publication date for a `Blog Post` content type:
+
+```js
+import { parseDateFromCatalog } from '@kitconcept/volto-light-theme/helpers/dates';
+import FormattedDate from '@plone/volto/components/theme/FormattedDate/FormattedDate';
+
+const BlogPostSummary = (props) => {
+  const { item, HeadingTag = 'h3' } = props;
+
+  const effective = parseDateFromCatalog(item.effective);
+  const headline = [
+    effective ? (
+      <FormattedDate
+        key="day"
+        date={effective}
+        format={{
+          year: 'numeric',
+          month: 'long',
+          day: 'numeric',
+        }}
+        className="day"
+      />
+    ) : null,
+    item.head_title,
+  ]
+    .filter((x) => x)
+    .flatMap((x) => [' | ', x])
+    .slice(1);
+
+  return (
+    <>
+      {headline.length ? <div className="headline">{headline}</div> : null}
+      <HeadingTag className="title">
+        {item.title ? item.title : item.id}
+      </HeadingTag>
+      {!item.hide_description && (
+        <p className="description">{item.description}</p>
+      )}
+    </>
+  );
+};
+
+export default BlogPostSummary;
+```
+
+The custom summary component must be registered in the Volto registry in your add-on's `applyConfig` function.
+For example, this registers the `BlogPostSummary` component as the summary to be used for a custom content type named `Blog Post`:
+
+```js
+import BlogPostSummary from 'volto-my-add-on/components/Summary/BlogPostSummary';
+
+const applyConfig = (config) => {
+  config.registerComponent({
+    name: 'Summary',
+    component: BlogPostSummary,
+    dependencies: ['Blog Post'],
+  });
+};
+```
+
+## Use the summary component
+
+You can use the `Summary` component to render a content type anywhere that the summary serialization is available (such as from `items` in the Plone REST API, or the results from the `@querystring-search` endpoint).
+
+Use it like this:
+
+```js
+import config from '@plone/volto/registry';
+import DefaultSummary from '@kitconcept/volto-light-theme/components/Summary/DefaultSummary';
+
+const Summary =
+  config.getComponent({
+    name: 'Summary',
+    dependencies: [item['@type']],
+  }).component || DefaultSummary;
+
+return <Summary item={item} />;
+```
