 ## 実行環境

-* PostgreSQL 9.6
+
+- PHP 7.1
+- PostgreSQL 9.6
+
+## 開発環境の構築
+
+Docker を用いた開発環境の構築方法です。
+
+1. `.env` ファイルを用意します。`.env.example` をコピーすることで用意ができます。
+
+2. Docker イメージをビルドします
+
+```
+docker-compose build
+```
+
+3. Docker コンテナを起動します。
+
+```
+docker-compose up -d
+```
+
+4. Composer と yarn を使い必要なライブラリをインストールします。
+
+```
+docker-compose exec web composer install
+docker-compose exec web yarn install
+```
+
+5. 暗号化キーの作成と、データベースのマイグレーションを行います。
+
+```
+docker-compose exec web php artisan key:generate
+docker-compose exec web php artisan migrate
+```
+
+6. ファイルに書き込めるように権限を設定します。
+
+```
+docker-compose exec web chown -R www-data /var/www/html/storage
+```
+
+7. アセットをビルドします。
+
+```
+docker-compose exec web yarn dev
+```
+
+
+8. 最後に `.env` を読み込み直すために起動し直します。
+
+```
+docker-compose up -d
+```
+
+これで準備は完了です。Tissue が動いていれば `http://localhost:4545/` でアクセスができます。
+
+## デバッグ実行
+
+```
+docker-compose -f docker-compose.yml -f docker-compose.debug.yml up -d
+```
+
+で起動することにより、DB のポート`5432`を開放してホストマシンから接続できるようになります。
+
+## アセットのリアルタイムビルド
+`yarn watch`を使うとソースファイルを監視して差分があると差分ビルドしてくれます。フロント開発時は活用しましょう。
+```
+docker-compose run --rm web yarn watch
+```
+
+もしファイル変更時に更新されない場合は`yarn watch-poll`を試してみてください。  
+現在Docker環境でのHMRはサポートしてません。Docker外ならおそらく動くでしょう。  
+その他詳しくはlaravel-mixのドキュメントなどを当たってください。
+
+## phpunit によるテスト
+
+変更をしたらPull Requestを投げる前にテストが通ることを確認してください。  
+テストは以下のコマンドで実行できます。
+
+```
+docker-compose exec web composer test
+```
 
 ## 環境構築上の諸注意
-* 初版時点では、DBサーバとしてPostgreSQLを使うよう .env ファイルを設定するくらいです。  
-  当分、PostgreSQLから変える気はないので専用SQL等を平気で使います。
