 動作確認環境
 ============
 
-- Python 2.7.6
-- Python 3.3.1
-- PyPy 1.9.0
-- PyPy 2.2.0
+- Python 3.8.5
+- pytest 6.2.4

+※Python2は2020年1月にサポート終了(EOL)していますので、Python3をご利用ください。
 
 セットアップ
 ============
 
+以下のように実行して、環境を構築してください。
+
 .. code-block:: sh
 
-   $ pip install -r requirements.txt
+   $ git clone https://github.com/yattom/python_pytest.git
+   $ cd python_pytest
+   $ pip3 install -r requirements.txt
 
-**setup.py** を実行し
+テストを実行するには **pytest** コマンドを使います。
 
 .. code-block:: sh
 
-   $ python setup.py test
-   
+   $ pytest
    ...
-
