+## Native dependencies
+
+You will need to install `lottie-ios` and `lottie-react-native` in order to use default animation provided, otherwise it will fallback to text based typing animation.
+
+:::tip
+  Install native dependencies only if you are going to use default typing animation.

+renderTypingBubble={() => <Text>Custom View (Typing...)</Text>}
+
+## Customize
+
+Pass `renderTypingBubble` at Chatty instance.
+
+```jsx
+import React, { useState } from 'react';
+import { Chatty } from 'react-native-chatty';
+
+export default function MyReactPage() {
+
+  return (
+    <Chatty
+      {...props}
+
+      // If you want to render whole custom animation
+      renderTypingBubble={() => <Text>Custom View (Typing...)</Text>}
+
+      // Or if you want to use default animation but want's to change the container
+      // You can grab default animation from the context, and use it that way too!.
+      renderTypingBubble={({ typingAnimation }) => <View style={fancyStyles}>{typingAnimation}</View>}
+    />
+  );
+}
