-git clone https://github.com/sqlalchemy/sqlalchemy.git $sqlAlchemyFolder

-pip install -e $sqlAlchemyFolder
+pip install -e $path_to_your_sqlalchemy_local_folder
 ```
 
 The `launch.json` file already has the required `"justMyCode": false` configuration which allows you to step into SQLAlchemy source files during debugging.
