+# プロバイダー
+
+バージョン `0.0.2` で実装される認証プロバイダー機能です。
+
+プロバイダーの設定をすることで、ログインしていないユーザーに特定の制限を設定できます。
+
+```ts
+type ConfigProps = {
+  noLogin: {
+    redirect?: string;
+    function?: () => void;
+    children?: React.ReactNode;
+  };
+};
+```
+
+制限したい要素の親要素に、`ScratchAuthProvider` を設置してください。
+
+```tsx
+// /src/app/dashboard/layout.tsx
+import ScratchAuthProvider from "@scratch-auth/nextjs/src/components/provider";
+
+export default function DashboardLayout({
+  children,
+}: Readonly<{
+  children: React.ReactNode;
+}>) {
+  return <ScratchAuthProvider>{children}</ScratchAuthProvider>;
+}
+```
+
+ログインしているユーザーは認証プロバイダーで制限されている要素を表示することができます。
+
+```tsx
+// /src/app/dashboard/page.tsx
+import React from 'react'
+
+function page() {
+  return (
+    <div>page</div>
+  )
