+Preact components for responsive images: Picture and Image.
+
+- 🖼 `<picture>` sources grouped by mime type and ordered by format efficiency
+- 🚀 Lazy loading and async decoding by default, `priority` for above-the-fold images
+- 🌫 Blur-up placeholder background until the image loads
+- 📐 Anti-CLS: intrinsic size from the image variant
+
+## Install
+
+```bash
+# pnpm
+pnpm add @srcset/preact @srcset/runtime
+# yarn
+yarn add @srcset/preact @srcset/runtime
+# npm
+npm i @srcset/preact @srcset/runtime
+```
+
+## Usage
+
+```tsx
+import { src, srcSet, placeholder } from './photo.jpg'
+import { Picture, Image } from '@srcset/preact'
+
+function Hero() {
+  return (
+    <Picture srcSet={srcSet}>
+      <Image
+        alt='Hero photo'
+        src={src}
+        placeholder={placeholder}
+      />
+    </Picture>
+  )
+}
+```
