+# Firebase Cloud Functions Development
+Cloud Functionsの開発環境
+
+## Requirements
+
+| Tools        | Version |
+| ------------ | ------- |
+| Firebase CLI | 8.4.1   |
+| Node.js      | 10  |
+| Typescript   | 3.9.5   |
+
+
+## 開発環境構築
+
+* ローカル環境の保護、依存性管理のためにDockerの利用
+* コンテナ内での開発効率化のために、[VS Code Remote Development](https://code.visualstudio.com/docs/remote/containers) を利用
+
+### Dockerのセットアップ
+1. [Docker Desktop for Windows/Mac](https://www.docker.com/products/docker-desktop)をインストール
+2. Dockerタスクバー項目を右クリックして、`Preferences > Shared Drives / File Sharing` からコンテナで開くソースコードの場所を追加する
+
+### VSCodeのセットアップ
+1. [Visual Studio Code](https://code.visualstudio.com/)をインストール
+2. [Remote Developmentプラグイン](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.vscode-remote-extensionpack)をVSCodeにインストール
+3. VSCodeを起動し、コマンドパレット(⇧⌘P)から`Remote-Containers: Open Folder in Container`を選択し、cloneしたディレクトリを開く
+    - `docker build`が実行されるので少し時間がかかります
+4. Firebase CLIにログイン
+    - VSCodeでターミナルを起動すればコンテナ内のシェルが起動する
+    - `$ firebase login`
