+## Local-First News
+
+The news runtime lives in `src-tauri/src/news/` and stores feed state plus articles in a local SQLite database under the app data directory. Reads are local-first: the UI and `/news` terminal command render cached articles immediately, while refreshes update the local cache in the background.
+
+Frontend example:
+
+```ts
+import { useNewsFeed } from './src/news';
+
+const { articles, refresh, toggleSaved, markRead } = useNewsFeed({
+  onlyHighlighted: true,
+  limit: 20,
+});
+```
+
+Terminal usage:
+
+```text
+/news
+/news NVDA
+```
+
+`/news` never fetches the network at read time. It filters articles already persisted in the local news database.
