+
+## Use Expo Config Plugin for Font Loading
+
+Use the `expo-font` config plugin to embed fonts at build time instead of
+`useFonts` or `Font.loadAsync`. Embedded fonts are more efficient.
+
+**Incorrect (async font loading):**
+
+```tsx
+import { useFonts } from 'expo-font'
+import { Text, View } from 'react-native'
+
+function App() {
+  const [fontsLoaded] = useFonts({
+    'Geist-Bold': require('./assets/fonts/Geist-Bold.otf'),
+  })
+
+  if (!fontsLoaded) {
+    return null
+  }
+
+  return (
+    <View>
+      <Text style={{ fontFamily: 'Geist-Bold' }}>Hello</Text>
+    </View>
+  )
+}
+```
+
+**Correct (config plugin, fonts embedded at build):**
+
+```json
+// app.json
+{
+  "expo": {
+    "plugins": [
+      [
+        "expo-font",
+        {
+          "fonts": ["./assets/fonts/Geist-Bold.otf"]
+        }
+      ]
+    ]
+  }
+}
+```
+
+```tsx
+import { Text, View } from 'react-native'
+
+function App() {
+  // No loading state needed—font is already available
+  return (
+    <View>
+      <Text style={{ fontFamily: 'Geist-Bold' }}>Hello</Text>
+    </View>
+  )
+}
+```
+
+After adding fonts to the config plugin, run `npx expo prebuild` and rebuild the
+native app.
