* 基本的なユーザーモデル (任意の修正や削除が可能)。
* **Alembic** マイグレーション。
* **CORS** (Cross Origin Resource Sharing (オリジン間リソース共有))。
* **Celery** ワーカー。バックエンドの残りの部分からモデルとコードを選択的にインポートし、使用可能。
* Dockerと統合された**Pytest**ベースのRESTバックエンドテスト。データベースに依存せずに、全てのAPIをテスト可能。Docker上で動作するので、毎回ゼロから新たなデータストアを構築可能。(ElasticSearch、MongoDB、CouchDBなどを使用して、APIの動作をテスト可能)
* Atom HydrogenやVisual Studio Code Jupyterなどの拡張機能を使用した、リモートまたはDocker開発用の**Jupyterカーネル**との簡単なPython統合。

**5. Copy to Google Internal codebase and run internal CI**

-   Once the PR is in the Google codebase, we make sure it integrates well with
    its dependencies and the rest of the system.
-   Rarely, If the tests fail at this stage, we cannot merge the code.
-   If needed, we may come to you to make some changes. At times, it may not be
