+---
+
+# Shiki Magic Move
+
+Animate code changes with smooth transitions (like Keynote's Magic Move).
+
+## Basic Usage
+
+`````md
+````md magic-move
+```js
+console.log(`Step ${1}`)
+```
+```js
+console.log(`Step ${1 + 1}`)
+```
+```ts
+console.log(`Step ${3}` as string)
+```
+````
+`````
+
+Note: Use 4 backticks for the wrapper.
+
+## With Line Highlighting
+
+`````md
+````md magic-move {at:4, lines: true}
+```js {*|1|2-5}
+let count = 1
+function add() {
+  count++
+}
+```
+
+Non-code blocks in between are ignored.
+
+```js {*}{lines: false}
+let count = 1
+const add = () => count += 1
+```
+````
+`````
+
+## How It Works
+
+- Wraps multiple code blocks as one
+- Each block is a "step"
+- Morphs between steps on click
+- Syntax highlighting preserved during animation
