-## React Directives
-
-These are React directives, not Next.js specific.
-
-### `'use client'`
-
-Marks a component as a Client Component. Required for:
-- React hooks (`useState`, `useEffect`, etc.)
-- Event handlers (`onClick`, `onChange`)
-- Browser APIs (`window`, `localStorage`)
-
-```tsx
-'use client'
-
-import { useState } from 'react'
-
-export function Counter() {
-  const [count, setCount] = useState(0)
-  return <button onClick={() => setCount(count + 1)}>{count}</button>
-}
-```
-
-Reference: https://react.dev/reference/rsc/use-client
-
-### `'use server'`
-
-Marks a function as a Server Action. Can be passed to Client Components.
-
-```tsx
-'use server'
-
-export async function submitForm(formData: FormData) {
-  // Runs on server
-}
-```
-
-Or inline within a Server Component:
-
-```tsx
-export default function Page() {
-  async function submit() {
-    'use server'
-    // Runs on server
-  }
-  return <form action={submit}>...</form>
-}
-```

-## Next.js Directive
-
-### `'use cache'`
-
-Marks a function or component for caching. Part of Next.js Cache Components.
-
-```tsx
-'use cache'
-
-export async function getCachedData() {
-  return await fetchData()
-}
-```
-
-Requires `cacheComponents: true` in `next.config.ts`.
-
