## ステップバイステップガイド

delegation と undelegation 用 instruction を呼び出す有効なトランザクションを組み立てます。
このプロジェクトの完全なテストは [Typescript Test Script](https://github.com/magicblock-labs/magicblock-engine-examples/blob/main/rust-counter/tests) にあります。

<Steps>
  <Step title={<a href="#1-connection">SDK をインポートし Connection を初期化する</a>}>
    connection とアカウントをセットアップする
  </Step>

  <Step title={<a href="#2-delegate">Base Layer で PDA を Delegate する</a>}>
    Base Layer 上で状態アカウントを委任する CPI hook をテストする

    <Note>
      <p>
        これらの公開バリデータは開発用として利用できます。委任命令には、
        対象となる ER バリデータを必ず追加してください。
