+
+## Use Galeria for Image Galleries and Lightbox
+
+For image galleries with lightbox (tap to fullscreen), use `@nandorojo/galeria`.
+It provides native shared element transitions with pinch-to-zoom, double-tap
+zoom, and pan-to-close. Works with any image component including `expo-image`.
+
+**Incorrect (custom modal implementation):**
+
+```tsx
+function ImageGallery({ urls }: { urls: string[] }) {
+  const [selected, setSelected] = useState<string | null>(null)
+
+  return (
+    <>
+      {urls.map((url) => (
+        <Pressable key={url} onPress={() => setSelected(url)}>
+          <Image source={{ uri: url }} style={styles.thumbnail} />
+        </Pressable>
+      ))}
+      <Modal visible={!!selected} onRequestClose={() => setSelected(null)}>
+        <Image source={{ uri: selected! }} style={styles.fullscreen} />
+      </Modal>
+    </>
+  )
+}
+```
+
+**Correct (Galeria with expo-image):**
+
+```tsx
+import { Galeria } from '@nandorojo/galeria'
+import { Image } from 'expo-image'
+
+function ImageGallery({ urls }: { urls: string[] }) {
+  return (
+    <Galeria urls={urls}>
+      {urls.map((url, index) => (
+        <Galeria.Image index={index} key={url}>
+          <Image source={{ uri: url }} style={styles.thumbnail} />
+        </Galeria.Image>
+      ))}
+    </Galeria>
+  )
+}
+```
+
+**Single image:**
+
+```tsx
+import { Galeria } from '@nandorojo/galeria'
+import { Image } from 'expo-image'
+
+function Avatar({ url }: { url: string }) {
+  return (
+    <Galeria urls={[url]}>
+      <Galeria.Image>
+        <Image source={{ uri: url }} style={styles.avatar} />
+      </Galeria.Image>
+    </Galeria>
+  )
+}
+```
+
+**With low-res thumbnails and high-res fullscreen:**
+
+```tsx
+<Galeria urls={highResUrls}>
+  {lowResUrls.map((url, index) => (
+    <Galeria.Image index={index} key={url}>
+      <Image source={{ uri: url }} style={styles.thumbnail} />
+    </Galeria.Image>
+  ))}
+</Galeria>
+```
+
+**With FlashList:**
+
+```tsx
+<Galeria urls={urls}>
+  <FlashList
+    data={urls}
+    renderItem={({ item, index }) => (
+      <Galeria.Image index={index}>
+        <Image source={{ uri: item }} style={styles.thumbnail} />
+      </Galeria.Image>
+    )}
+    numColumns={3}
+    estimatedItemSize={100}
+  />
+</Galeria>
+```
+
+Works with `expo-image`, `SolitoImage`, `react-native` Image, or any image
+component.
