 ## 構成
-* Laravel 5.5

 ## 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 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
+```
+
+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
+```
+
+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。
 
 ## 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。
