+# Shiki Magic Move
+
+Powered by [shiki-magic-move](https://shiki-magic-move.netlify.app/), Slidev supports animations across multiple code snippets.
+
+Add multiple code blocks and wrap them with <code>````md magic-move</code> (four backticks) to enable the magic move. For example:
+
+````md magic-move {lines: true}
+```ts {*|2|*}
+// step 1
+const author = reactive({
+  name: 'John Doe',
+  books: [
+    'Vue 2 - Advanced Guide',
+    'Vue 3 - Basic Guide',
+    'Vue 4 - The Mystery'
+  ]
+})
+```
+
+```ts {*|1-2|3-4|3-4,8}
+// step 2
+export default {
+  data() {
+    return {
+      author: {
+        name: 'John Doe',
+        books: [
+          'Vue 2 - Advanced Guide',
+          'Vue 3 - Basic Guide',
+          'Vue 4 - The Mystery'
+        ]
+      }
+    }
+  }
+}
+```
+
+```ts
+// step 3
+export default {
+  data: () => ({
+    author: {
+      name: 'John Doe',
+      books: [
+        'Vue 2 - Advanced Guide',
+        'Vue 3 - Basic Guide',
+        'Vue 4 - The Mystery'
+      ]
+    }
+  })
+}
+```
+
+Non-code blocks are ignored.
+
+```vue
+<!-- step 4 -->
+<script setup>
+const author = {
+  name: 'John Doe',
+  books: [

+
+You can use Vue components directly inside your slides.
+
+We have provided a few built-in components like `<Tweet/>` and `<Youtube/>` that you can use directly. And adding your custom components is also super easy.
+
+```html
+<Counter :count="10" />
+```
+
+<!-- ./components/Counter.vue -->
+<Counter :count="10" m="t-4" />

+# Themes
+
+Slidev comes with powerful theming support. Themes can provide styles, layouts, components, or even configurations for tools. Switching between themes by just **one edit** in your frontmatter:
+
+<div grid="~ cols-2 gap-2" m="t-2">
+
+```yaml
+---
+theme: default

+
+```yaml

+
+# Clicks Animations
+
+You can add `v-click` to elements to add a click animation.
+
+<div v-click>
+
+This shows up when you click the slide:
+
+```html
+<div v-click>This shows up when you click the slide.</div>
+```
+
+</div>
+
+<br>
+
+<v-click>
+
+The <span v-mark.red="3"><code>v-mark</code> directive</span>
+also allows you to add
+<span v-mark.circle.orange="4">inline marks</span>
+, powered by [Rough Notation](https://roughnotation.com/):
+
+```html
+<span v-mark.underline.orange>inline markers</span>

+# Monaco Editor
+
+Slidev provides built-in Monaco Editor support.
+
+Add `{monaco}` to the code block to turn it into an editor:
+
+```ts {monaco}
+import { ref } from 'vue'
+import { emptyArray } from './external'
+
+const arr = ref(emptyArray(10))
+```
+
+Use `{monaco-run}` to create an editor that can execute the code directly in the slide:
+
+```ts {monaco-run}
+import { version } from 'vue'
+import { emptyArray, sayHello } from './external'
+
+sayHello()
+console.log(`vue ${version}`)
+console.log(emptyArray<number>(10).reduce(fib => [...fib, fib.at(-1)! + fib.at(-2)!], [1, 1]))
