+## September 2025 - Registry Index
+
+We've created an index of open source registries that you can install items from.
+
+You can search, view and add items from the registry index without configuring the `.components.json` file.
+
+They'll be automatically added to your `components.json` file for you.
+
+```bash
+npx shadcn add @ai-elements/prompt-input
+```
+
+The full list of registries is available at [https://ui.shadcn.com/r/registries.json](https://ui.shadcn.com/r/registries.json).
+
+To add a registry to the index, submit a PR to the `shadcn/ui` repository. See the [registry index documentation](/docs/registry/registry-index) for more details.
