+### Pre Processing
+
+It is possible to need to pre-process the data outside of this library ([related discussion here](https://github.com/iamacup/react-native-markdown-display/issues/79)). As a result, you can pass an AST tree directly as the children like this:
+
+```jsx
+import React from 'react';
+import { SafeAreaView, ScrollView, StatusBar, Text } from 'react-native';
+
+import Markdown, { MarkdownIt, tokensToAST, stringToTokens } from 'react-native-markdown-display';
+
+const markdownItInstance = MarkdownIt({typographer: true});
+
+const copy = `
+# Hello this is a title
+
+This is some text with **BOLD!**
+`;
+
+const ast = tokensToAST(stringToTokens(copy, markdownItInstance))
+
+const App: () => React$Node = () => {
+  return (
+    <>
+      <StatusBar barStyle="dark-content" />
+      <SafeAreaView>
+        <ScrollView
+          contentInsetAdjustmentBehavior="automatic"
+          style={{height: '100%'}}
+        >
+            <Markdown
+            >
