 ## What is json-render?
 
-json-render is the framework for **User-Generated Interfaces**: dynamic UIs that end users generate through natural language prompts, powered by Generative UI. You define the guardrails: what components exist, what props they take, what actions are available. AI generates JSON that matches your schema, and your components render it natively on web or mobile.

 # Registry
 
-Register React components and action handlers to bring your catalog to life.
+A registry maps your [catalog](/docs/catalog) definitions to platform-specific implementations. The catalog defines *what* AI can generate — the registry provides the *how*.
 
-## defineRegistry
+What a registry contains depends on the schema you use. Each package defines its own schema, which determines the shape of both the catalog and the registry.
 
-Use `defineRegistry` to create a type-safe registry from your catalog. Pass your components, actions, or both in a single call:

+## @json-render/react-native
+
+`@json-render/react-native` uses the same `defineRegistry` API. The only difference is that components return React Native elements instead of HTML:
+
+```tsx
+import { defineRegistry } from '@json-render/react-native';
+import { View, Text, Pressable } from 'react-native';
+
+export const { registry } = defineRegistry(catalog, {
+  components: {
+    Card: ({ props, children }) => (
+      <View style={styles.card}>
+        <Text style={styles.title}>{props.title}</Text>
+        {children}
+      </View>
+    ),
+
+    Button: ({ props, emit }) => (
+      <Pressable onPress={() => emit?.("press")}>
+        <Text>{props.label}</Text>
+      </Pressable>
+    ),
+  },
+});
+```
+
+See the [@json-render/react-native API reference](/docs/api/react-native) for the full API.
+
+## @json-render/remotion
+
+`@json-render/remotion` takes a different approach. Instead of `defineRegistry`, it uses a plain component registry with built-in standard components for video production:
+
+```tsx
+import { Renderer, standardComponents } from '@json-render/remotion';
+
+// Use the standard components directly
+<Renderer spec={timelineSpec} components={standardComponents} />
+
+// Or extend with your own
+const components = {
+  ...standardComponents,
+  CustomSlide: ({ clip }) => <AbsoluteFill>{/* ... */}</AbsoluteFill>,
+};
+```
+
+The Remotion schema also supports `transitions` and `effects` in the catalog rather than actions.
+
+See the [@json-render/remotion API reference](/docs/api/remotion) for the full API.
