+
+Motion for Vue is an open source, production-ready library that’s designed for all creative developers.
+
+It's the only animation library with a hybrid engine, combining the power of JavaScript animations with the performance of native browser APIs.
+
+It looks like this:
+
+```jsx
+<motion.div :animate="{ x: 100 }" />
+```
+
+It does all this:
+
+- Springs
+- Keyframes
+- Layout animations
+- Shared layout animations
+- Gestures (drag/tap/hover)
+- Scroll animations
+- SVG paths
+- Exit animations
+- Server-side rendering
+- Independent transforms
+- Orchestrate animations across components
+- CSS variables
+
+...and a whole lot more.
+
+## Get started
+
+### 🐇 Quick start
+
+Install `motion-v` via your package manager:
+
+```
+npm install motion-v
+```
+
+Then import the `motion` component:
+
+```vue
+<script setup>
+import { motion } from 'motion-v'
+</script>
+
+<template>
+  <motion.div :animate="{ x: 100 }" />
+</template>
+```
